Description
Technical field
The invention belongs to two-dimension cartoon making technical field, more particularly to a kind of limb member model, role and two dimension
The method of cartoon making.
Background technology
So-called animation, refer to just by it is a series of possess slight change, static picture continuously played with certain rate,
A kind of illusion of the picture dynamic change generated by naked eyes persistence of vision effect.The process of existing cartoon making is substantially counted
Calculation machine technology is combined with traditional animation manufacturing technology, and computer technology is applied in the production process of animation, it is intended to by
Advanced computer technology frees people from the animation process of lengthy and tedious complexity, reduces manpower and materials to greatest extent
Input, shorten the cartoon making time to improve producing efficiency, to achieve the purpose that reduce cost of manufacture.
Existing computer animation generally comprises：Between three-dimensional animation, skeleton cartoon, paint animation, element animation and benefit
Animation.Wherein：
Three-dimensional animation is the most typical with Maya softwares, is to initially set up a virtual world in a computer, design
Teacher establishes model and scene in this virtual three-dimensional world according to the geomery for the object to be showed, further according to requiring
The movement of the movement locus, virtual camera of setting model and other animation parameters are finally that model is assigned to specifically as required
Material, and stamp light renders after the completion of everything and generates last picture, due to its accuracy, authenticity and unlimited
Operability, three-dimensional animation production is able to large range of application, but this animation method first matches computer
It sets and requires high, and the design level of designer will also reach very high level, so as to cause that can not popularize.
Skeleton cartoon is to establish the skeleton structure for having and interconnecting " bone " composition using Spine softwares as representative,
Animation is generated for model by changing direction and the position of bone, therefore, skeleton cartoon is monomorphism structure, not polymorphic
Middle transition, and the variation of multi-angle cannot be completed, it is difficult to give visual impact.
Paint animation is drawn the lines figure of cartoon role, is then passed through to lines figure first using Animo softwares as representative
High speed scanner scans and recognizes progress color in computer and specifies, and finally paints again to the image after scanning, process is numerous
Multiple, workload is very big.
Element animation most typically surely belongs to flash animation Software for producing, and cartoon making is realized in the movement by building element
Process, it is at low cost, but consecutive variations are unable to inside its element, it can only be poor by smart option variation picture continuity,
Influence visual effect.
Animation generates the intermediate frame of vector quantization by the way that key frame is arranged using CACAni as representative between benefit, dynamic to be formed
Manufacturing process is drawn, design is relatively simple, but the intermediate frame of vector quantization is in generating process, not all being ordered into shapes
At some intermediate frames and the visual custom for not meeting human eye influence visual effect.
Invention content
For the above deficiency, one of the objects of the present invention is to provide a kind of limb member models, less by designing
The external morphology of quantity can generate the change shape of limb member model by way of orderly changing, to form the limbs

It is not high, it is conducive to promote.
To achieve the goals above, the present invention is realized by following technical proposal：
A kind of limb member model, the limb member model exist in the form of limb member, limb member model by
Several external morphologies form, by orderly changing mutual conversion between any two external morphology, wherein the two is mutually turning
Change the external morphology that the change shape formed in the process also constitutes the limb member model.
The external morphology is figure of the limb member on each time point, and the figure is folded by multilayer color lump and subcomponent
Add, has on every layer and only there are one color lump or subcomponents.
The orderly variation mutually converted between any two external morphology meets the following conditions：
Equivalent layer is color lump or subcomponent between two external morphologies and the change shape of the two；
If the equivalent layer is color lump, the node total number all same of the color lump in equivalent layer, and between node one by one
It is corresponding.
The limb member model includes at least head model, upper limb model, lower limb model and human trunk model；
The external morphology of the head model further includes several expression unit, and each expression unit includes the front on head
Form and side form；The figure of head model is divided into eye control part and mouth control part, the color of each layer in the figure of head model
Block and subcomponent are intended to unambiguously belong to eye control part or mouth control part；
The external morphology of the upper limb model includes that several rotate the figure formed by forearm around ancon, and forearm surrounds
Ancon completes 0-360 ° of rotation and constitutes the complete external morphology of upper limb model；
The external morphology of the lower limb model includes several rotates the figure formed around knee point by calf circumference, calf circumference around
Knee point completes 0-360 ° of rotation and constitutes the complete external morphology of lower limb model；
The external morphology of the human trunk model includes trunk longitudinal stretching and the figure that compression is formed, and trunk is rotated from left-hand
0-90 ° is turned left to dextrad, trunk and trunk turns right 0-90 ° and constitutes the complete external morphology of the human trunk model.
By taking upper limb model as an example, the external morphology of upper limb model includes that several rotate the figure formed by forearm around ancon
Shape, figure here refers to the basic external morphology of the upper limb model designed in advance, for example, upper limb model includes its forearm and elbow
The angle formed between portion is in the basic external morphology such as 0 °, 45 °, 90 °, 135 °, 180 ° and 270 ° respectively, these are substantially internal
It can be converted by way of orderly changing between form any two, the arbitrary variation that orderly variation is formed therebetween
Realize that forearm completes the rotation in Partial angle, multiple continuous parts around ancon together with form and these basic external morphologies
The set of rotation in angle constitutes the complete external morphology of upper limb model, and (complete external morphology includes substantially internal
Form and change shape).For example, upper limb model can be realized by orderly changing in the basic external morphology of 0 ° and 45 ° of upper limb model
0-45 ° of rotation constitutes the external morphology within the scope of 0-45 ° of the upper limb model, orderly change between other angles it is similar therewith, from
And form the rotation that upper limb model forearm surrounds 0-360 ° of ancon.
Another object of the present invention is to provide a kind of cartoon role, posture is presented by multiple limbs and composition is presented,
The design of role, design letter can be completed in the external morphology that corresponding limb member model is presented by the different limbs of selection
Single, workload substantially reduces, and the requirement to designer and allocation of computer is not high, is conducive to promote.
To achieve the goals above, the present invention is realized by following technical proposal：
A kind of cartoon role, the role are made of several limb members, the posture of a role at some time point
It presents and is made of the presentation of the limbs of several limb members, the limbs are rendered as the outside of each limb member at the time point
Track and external morphology, the outer trace of the limb member be each limb member at the time point corresponding coordinate, size with
And angle, by orderly changing mutual conversion between the external morphology at limb member each time point.
The external morphology of each limb member from its corresponding limb member model external morphology (including substantially in
Portion's form and change shape) in choose, any two external morphology is (for the limb member mould designed in advance in limb member model
The basic external morphology of type) between by orderly changing mutual conversion, wherein both the variation that is formed in mutual transfer process
Form also constitutes the external morphology of the limb member model.
The method chosen from the external morphology in its corresponding limb member model from the external morphology of each limb member
It is：If the external morphology for choosing limb member is the basic external morphology of limb member model, it is basic directly to choose this
External morphology then passing through two conversely, when the external morphology that choose limb member is not belonging to a kind of in basic external morphology
It is chosen in multiple change shapes that the orderly variation pattern of basic external morphology generates.
Such as the internal state of upper limb element is chosen, then first find out upper limb mould corresponding with the upper limb element
Type, it is assumed that the upper limb model include the angle that is formed between its forearm and ancon be in respectively 0 °, 45 °, 90 °, 135 °, 180 ° and
The basic external morphologies such as 270 °, and if the external morphology that choose upper limb element is forearm and the external morphology that hand is in 45 °
When, then directly chosen from the basic external morphology of upper limb model, if to choose upper limb element external morphology be forearm with
When hand is 70 ° of external morphology, then just need first to choose the basic external morphology of 45 ° and 90 ° of upper limb model, then should
45 ° and 90 ° of basic external morphology carries out orderly variation and forms change shape between the two, finally in these change shapes
Find internal state of the forearm with hand in the change shape of 70 ° (or close to 70 °) as the upper limb element to be chosen.
Limbs of each limb member on any two time point are presented by orderly variation mutually conversion, become among the two
Change limbs presentation to be made of the variation of the track linear change and external morphology of each limb member.
Two time points upper corresponding limb member external morphology and external morphology variation have multilayer color lump and son
Element is superimposed to be formed, and has on every layer and only there are one color lump or subcomponents, each limb member is on any two time point
Limbs be presented by orderly variation mutually conversion meet：
Equivalent layer between two time points upper corresponding limb member external morphology and the external morphology variation of the two
It is color lump or subcomponent；
If the equivalent layer is color lump, the node total number all same of the color lump in equivalent layer, and between node one by one
It is corresponding.
The present invention also provides a kind of two-dimension cartoon making method, by design small number of limb member model and
(basic) internal state of each limb member model, and choose the internal state composition of limb member model and limb member model
The character pose of Each point in time, then these character poses are carried out continuously, to realize the making of animation, design is simple,
Workload substantially reduces, and the requirement to designer and allocation of computer is not high, is conducive to promote.
To achieve the goals above, the present invention is realized by following technical proposal：
A kind of two-dimension cartoon making method comprising following steps：
Multiple limb member models of each limb member are drawn, each limb member model has multiple external morphologies, limb again
By orderly changing mutual conversion between any two external morphology in body component models, wherein the two is in mutual transfer process
The change shape of formation also constitutes the external morphology of the limb member model；
Suitable limb member model, combination is selected to form role；
It is required according to character pose, the limbs for choosing each limb member are presented, and the limbs of each limb member are presented on
Corresponding time point is put, and the character pose includes that the expression of role and posture are presented；
Limbs by orderly changing each limb member between generating arbitrary two adjacent angulars color posture are presented, and complete role
The consecutive variations of posture carry out flash demo by playback head.
The character pose require to be realized by putting role framework and mark role's expression in different time points,
In, the limbs presentation of each limb member that role framework and the time point that each time point is put put is corresponding.
In the present invention, the data of animation process or flow have distinct hierarchical structure, by limbs model element → angle
Color → role's posture illustrates：The limb member of composition role A has limb member B, C, D and E, and assume limb member B,
C, D and E is by several limb member models (limb member B is made of limb member Model B 1, B2, B3 ...), meanwhile, often
A limb member model is made of multiple external morphologies (assuming that limb member Model B 1 is by external morphology B11, B12, B13 group again
At), then, for role A, by diversified forms, ensure that the diversification of role, for example, limb member Model B 1, C1,
D1 and E1 constitutes role A1, and limb member Model B 2, C1, D1 and E1 constitute role A2 ..., and angle at some time point
The posture of color can be diversification again, can be limb member for example, for a posture of role A1 presentation A11
The external morphology B11 of Model B 1, the external morphology C11 of limb member MODEL C 1, limb member model D1 external morphology D11,
The external morphology E11 of limb member model E 1 while the outer trace and role's expression composition for adding these limb members,
And we are when designing, it is only necessary to make the limb member model of each limb member and several bases of each limb member model
This external morphology can form different roles by different combinations and role's posture is presented.
Compared with prior art, the present invention having the following advantages that：
1, high efficiency
The outstanding advantage of the present invention is high cartoon making efficiency, since any one role's picture is all to pass through limb
The presentation of volume elements part and generate, so any picture need not manually be drawn.Production method with current 2D animations circle prevalence is
Example, the workload that a skilled worker animation teacher draws role is the 40/day for human beings, 2 seconds role animations can be about made, using we
Method only needs the posture for being well placed each time point, computer that can automatically generate picture, can substantially make role animation 2 daily and divide
Clock.
2, simplification
As described above, character pose puts the core for making work as action, it includes body appearance to put character pose
The outstanding feature of the mark of state put with expression, this two work is intuitive, clear, avoids the required hand of traditional approach
Basis and experience are painted, the software knowledge and concept of the large amount of complex of 3D computer animation to master are also avoided.Briefly, make
Animation is simple as speaking.
3, the advantages of multi-level combination
It can be seen from the above, the invention mainly comprises 3 steps (or 3 levels for data structure), limbs model
The generation of animation is built, is acted in drafting, the combination of role.These three steps the former be the latter basis, and can independently of each other,
Work separation.A good art designing is only needed to draw limb member this means that making a cartoon, in other words a Gao Shui
Flat art designing, it is high-caliber art designing that can copy all producers all in the present invention.Remaining most work amount
Animation producing work do not need art designing or have a professional person of art accomplishment, animation producing personnel or Performance Animation personage are only
It needs to set posture appropriate in reasonable time point, the work of role's performance can be absorbed in this way, can preferably be held
The rhythm of action, exaggeration, expression.And it acts, the common fault of not lively enough the fine and smooth exactly current domestic animation of expression.
In the present invention, it is the drafting of limbs model uniquely to need the work of Freehandhand-drawing, i.e., is painted under the requirement of three principles
Go out multiple internal representative configurations of limbs, this Freehandhand-drawing draws efficiency very with the help of being operated in dedicated computer-aided tool
Height is still a ring relatively cumbersome in three steps.But the work for the step for reuse of limbs model can be effectively save
Amount.The used limbs model of profit before can be used such as in the combination of a character is built, by the different arm of selection,
Leg, human trunk model and different relative scales, then changed colour by specific purpose tool and make role's one integrated mass, each role, which has, to cut
The so different bodily form and image.
Equally, although each role is different, it is unified to record the format of the data parameters of posture, so an angle
The action of color can be transplanted on another role, so the present invention (does not make claim, commonly comprising several action models
Action model is by walking, running, jump, look smug or conceited), the segment table of role drills the knot that often several action models are combined
Fruit.It, can will best most elaboration Reusability while effectively saving workload in this way.
What can be abstracted says, limb member, role build, posture is put etc., each step is all a kind of mistake of combination collocation
Journey, and the matched combined of different levels constitutes the unlimited possibility of virtual world.
4, the animation performance that actual situation combines
In investing not high 3D animations, the character of appearance often has the feeling of rubber doll, this is primarily due to carefully
Save not in place, 3D animations can be described as an analogue system, and ideal 3D animations need to simulate all details of real world,
Such as every hair, the texture of different parts skin, each wrinkle, creasing, it is clear that workload is astronomical figure.And it is of the invention
In, animation producing can be described as a matching process, and basic expressions unit is color lump, and lines have tended to color lump in other words
To with empty generation is real, vividly succinct effect of shiring the heavy work aning choose the light again.For example, an in disorder hair need not draw every hair, only
It needs that several pieces of deep mixed color lumps are added within the scope of hair style color lump, then several sharp keen color lumps is added at bang temples,
This image can be completed.Therefore it is taken by the lines or color lump that freehand brushwork in the present invention of basic expressions form, can be used of color lump
It is cumbersome to write real complexity.Accomplish this point, the innervation of 3D is true and the lucid and lively of 2D vividly can effectively be combined together.
5, the shortcomings that limbs combine effectively overcomes
Since role is combined by each limb member, the feeling of machinery is inevitably had, each limbs combination exists
All often lack a kind of feeling of total tune, briefly, somewhat like robot, overcome this disadvantage, are each limbs
Want flexible variation in linking part.For example, a role lifts arm, the protuberance of the triceps muscle of arm is had, due to color in the present invention
The variation of block is controllable, therefore after selection matches the respective inner form of limbs model, adjusts the color lump of junction
Form can effectively overcome the feeling of robot.From the present invention actual effect in terms of, total tune feel to be fully equivalent to it is pure
Freehandhand-drawing.
6, the great potential in the Internet, applications
It is multi-level based on limb member it is well known that internet is changing the life mode of production of human society
The cartoon making mode of combination, has suited that internet is shared, succinct feature.Just think, a people without any art activities,
As long as choosing limb member appropriate, constitute a role, in this embodiment it is not even necessary to choose limb member, can directly choose one or
Several roles, so that it may to allow him (s) to perform one section of story, express one section of emotion, cartoon making perhaps can be the same as blog is write
Simple popular daily behavior.Meanwhile limb member makes, role combinations collocation, stage property setting work, due to its simplification,
Have the participation of numerous users, it will it is available to provide magnanimity model.Optimistic says that the present invention is likely to become an interconnection
Online ecological environment.

It please refers to shown in Fig. 1, a kind of production method of 2 D animation comprising following steps：
One, multiple limb member models of each limb member of composition role are drawn.
Limb member model exists in the form of limb member, and each limb member of composition role (i.e. role's element) has
Multiple limb member models, this few limb member model are to design or designed accordingly as needed, example in advance
Such as, a limb member of the right arm element as role, the right upper arm of different length and the right forearm of different length be not plus
The right hand with size may be constructed many right arm elements.
Each limb member model has multiple external morphologies, these external morphologies are to be designed in advance, referred to herein as
Basic external morphology.By orderly changing mutual conversion between the basic external morphology of any two in limb member model, wherein
The external morphology that the change shape that the two is formed in mutual transfer process also constitutes the limb member model (is referred to as broad sense
External morphology), therefore, broad sense external morphology is made of basic external morphology and variation external morphology.
Limb member model includes at least head model, upper limb model (including right arm model and left arm model), lower limb mould
Type (including right leg model and left leg model) and human trunk model, corresponding limb member are head elements, upper limb element (packet
Include right arm element and left arm element), lower limb member (including right leg element and left leg element) and trunk element.
The external morphology of head model further includes several expression unit, and each expression unit includes the positive form on head
With side form；The figure of head model is divided into eye control part and mouth control part, in the figure of head model the color lump of each layer and
Subcomponent is intended to unambiguously belong to eye control part or mouth control part.The external morphology of upper limb model includes that several are surrounded by forearm
Ancon rotates the figure to be formed, and forearm completes 0-360 ° of rotation around ancon and constitutes the complete external morphology of upper limb model.
The external morphology of lower limb model includes that several rotate the figure formed around knee point by calf circumference, and calf circumference completes 0- around knee point
360 ° of rotations constitute the complete external morphology of lower limb model.The external morphology of human trunk model includes trunk longitudinal stretching and pressure
Contract the figure formed, and trunk turns to dextrad from left-hand, trunk turns left 0-90 ° and trunk turns right 0-90 ° of composition
The human trunk model complete external morphology.
By taking upper limb model as an example, the external morphology of upper limb model includes that several rotate the figure formed by forearm around ancon
Shape, figure here refers to the basic external morphology of the upper limb model designed in advance, for example, upper limb model includes its forearm and elbow
The angle formed between portion is in the basic external morphology such as 0 °, 45 °, 90 °, 135 °, 180 ° and 270 ° respectively, these are substantially internal
It can be converted by way of orderly changing between form any two, the arbitrary variation that orderly variation is formed therebetween
Realize that forearm completes the rotation in Partial angle, multiple continuous parts around ancon together with form and these basic external morphologies
The set of rotation in angle constitutes the complete external morphology of upper limb model, and (complete external morphology includes substantially internal
Form and change shape).For example, upper limb model can be realized by orderly changing in the basic external morphology of 0 ° and 45 ° of upper limb model
0-45 ° of rotation constitutes the external morphology within the scope of 0-45 ° of the upper limb model, orderly change between other angles it is similar therewith, from
And form the rotation that upper limb model forearm surrounds 0-360 ° of ancon.
Orderly change the process that in fact mainly color lump converts, the i.e. orderly variation of color lump in the present invention.
1, the meaning of color lump conversion
In the present invention, limb member is to form the base unit of role, and color lump and subcomponent are composition limbs members
The variation of the base unit of part, a limb member model external morphology is by its internal deformation of color lump and the track of subcomponent
What variation determined.Therefore, the conversion between the color lump of different time points (also referred to as frame) is the basis that animation is realized.Only color lump
Conversion is normal complete, meets the vision common sense of people, just animation can be made to seem natural and tripping, otherwise, entire cartoon role is in
Now can not consecutive variations or unordered variation, the solid for being rendered as a pile and scarcely knowing what one has said of limb member makes one not understanding, from
Animation cannot so be constituted.Such as the eyebrow variation in Fig. 2.
2, the requirement converted
The intermediary (i.e. change shape) of conversion between two color lumps is unlimited various, and the angle realized from animation goes out
Hair, it is necessary to be the visual custom for meeting people, then what visual custom of people is, be analyzed by type exhaustion, it can be deduced that
Conclusion：Certain change type can be obviously summarized as by meeting the color lump variation of visual custom, and meet common physics law.Such as two
Variation between color lump can obviously judge the rotation of color lump, stretching, compression, bending, recess, protrusion, amplification, reduce variation.
For example, as shown in figure 3, a square variation is rectangular, it should be a drawing process, and cannot be by square deformation
At circle, then become rectangular.
In conclusion meeting visual custom, the conversion of color lump must satisfy the following conditions：
(1) the conversion process of color lump has uniqueness.I.e. intermediate change form is to determine simultaneously unique, unique master here
Refer to for limb member model, if a certain layer of its basic external morphology is color lump, intermediate change form
Equivalent layer also must be color lump, and the color lump of their equivalent layers have and only there are one, similarly, subcomponent is also unique.
(2) change in shape incrementss absolute value is minimum.I.e. intermediate change form with front and back color lump (front and back color lump here
For the color lump on equivalent layer in basic external morphology) increment variation it is minimum.
(3) intermediate color lump area is the linear change value of front and back color lump.I.e. the area of intermediate change form is between front and back color lump
Between area.
Any two intermediate change form can infinite approach, variation is continuous progressive.That is any two intermediate change
A certain change shape is equal to the change shape of front and back color lump at the time point between form.
By largely testing proof, meets the color lump conversion of above-mentioned condition, that is, meet visual custom, in the present invention, accord with
The color lump variation for closing above-mentioned condition is referred to as the orderly variation of color lump.
3, the inscape of color lump
To reach above-mentioned requirements, it is necessary to analyze the inscape of color lump.So-called color lump, only on the upper conversational implication of drawing
Saying, point or line, a circle or ellipse, an irregular solid with area, are color lump.Summarize various
After the essence of color lump type, concept can be summarized as：One physical presence or virtual closed curve (contour line) and its inside
The solid that certain color filling is constituted.Constitute being known as color lump：
(1) contour line, one and only one closed curve are contour line, and contour line can be with physical presence, also can be empty
Quasi- to exist, when its virtual presence, color lump shows as only shape filling, without the edge line of periphery package.
(2) node, contour line are made of several line segments, and line segment both ends are node, and node arranges in order, therefore every
A node has point sequence.Because contour line is to be closed, point sequence arrangement is cycle.The attribute of node is point sequence and two dimension
Geometric coordinate, as shown in Figure 4.
(3) line segment, connecting line is line segment between node, and the type of line segment has straight line and curve, is shellfish in the present invention
Sai Er curves, straight-line segment are a Bezier of special parameter, and curved segments are secondary Bezier.Its attribute has
Front end point coordinates, rear end point coordinates, control point coordinates, line sequence.Line sequence is equal to forward terminal point sequence.It should be noted that n times shellfish plug
Your curve can be analyzed to n secondary Beziers.
(4) fill color, the Fill Color inside contour line are fill color, inscape have color code, variation pattern,
Transformation matrices.
4, the mathematical model that color lump orderly changes
To make front and back color lump orderly change, as shown in figure 5, founding mathematical models meet the following conditions.
1. front and back color lump a and b be all have and only there are one, i.e. a color lump can only be converted into another color lump, and cannot one
A color lump becomes two, only meets this necessary condition, just can guarantee that in-between change shape is unique, in Software for Design
In realization, a figure layer can only have 1 color lump.
2. what the serial number of the node of front and back color lump was to determine, the node of front and back color lump keeps one-to-one relationship.
3. the variation path of node is not simply to move linearly, it is necessary to meet the gradual change of color lump area.
Xc≠Xa+k*(Xb-Xa)
Yc≠Ya+k*(Yb-Ya)
The step of seeking the node coordinate of intermediate color lump c is as follows：
(1) each node cathetus of color lump a is found out apart from maximum any two node Pam、Pan
(2) each node cathetus of color lump b is found out apart from maximum any two node Pbm、Pbn
(3) condition is met | PamPan|+|PbmPbn| it is more than other combination of nodes
(4) line segment PamPanConstitute the backbone of color lump a, line segment PbmPbnConstitute the backbone of color lump b.
(5) according to the linear change of the midpoint of a, b backbone line, angle and length, find out the midpoints of c backbones, angle and
Length.
(6), according to the difference of ab color lumps each node and backbone, the difference of c color lumps each node and backbone is calculated.
△Pic=△ Pia+k*(△Pib-△Pia)
(7), according to the difference of c backbones and each node, the coordinate of each node is calculated.
(8) make recursive operation to determine that area adjusts each node difference as desired value, calculate the coordinate of final each node.
4. due to known front and back extreme coordinates, as long as the curve shape of each line segment is determining to obtain its Bezier control points coordinate
, Bezier control points coordinate formula is：
P (j)=(1-j)2P0+2j(1-j)P1+j2P2
Wherein j ∈ (0,1), P0P2For front and back endpoint, P (j) is curvilinear path point, P1Point in order to control.
Work as PjFor P0P2The midpoint of straight-line segment and the line at control point and P0P2(the j=0.5 when intersection point of Bezier
When), can simplify formula is：
P1=2*Pj-(P0+P2)/2
Behind the control point for finding out the line sequence of front and back color lump, according to the variable difference at control point and front and back endpoint, in calculating
Between the color lump line sequence control point
△P1c=△ P1a+k*(△P1b-△P1a)
Wherein k ∈ (0,1) are amplitude of variation.
5. the Fill Color of the calculating of color change median, previous color lump a is Ca, the Fill Color of latter color lump b is
16 binary digits of the three-primary colours of color are converted to 10 binary digits by Cb, restore 16 system numbers of three-primary colours after linear operation
Word code.For the linear change that its color change value is front and back color lump color.
Cc=Ca+k* (Cb-Ca)
6. variance values are the intermediate forms of front and back color lump, it is generally the case that its amplitude of variation i.e. and time point
Amplitude of variation synchronizes, i.e.,
(Xc-Xa)/(Tc-Ta)=(Xb-Xa)/(Tb-Ta)
Xc=Xa+ (Xb-Xa) * (Tc-Ta)/(Tb-Ta)
But since color lump pace of change is with the presence of the factor (the referred to as slow-action for influencing amplitude of variation in this way similar to acceleration
Tw), therefore the calculating of median must take into consideration the presence of slow-action.Slow-action is front and back color using -1 to 1 amplitude proportional as metric
In period between block, the variation put at any time and change.
As tw ≠ 0, the variation formula of median is：
Xc=Xa+ (Xb-Xa) * (1+tw) * (Tc-Ta)/(Tb-Ta)
Arranged by above six geometry or calculated, a complete mathematical model is formed, so that it is determined that intermediate change color
The unique value of 4 elements of block.
5, code is realized
According to above-mentioned mathematical model, following three premises are must satisfy in animation：
1. a figure layer can only be there are one color lump.
2. the node total number of the color lump of different time points must be identical in a figure layer.
3. each node point sequence of the color lump of different time points is stable in a figure layer.
On the basis of this three, pass through 4 elements of color lump before and after reading, it may be determined that intermediate color lump on certain time point
The unique value of four elements.
Its code module is substantially
Two, suitable limb member model, combination is selected to form role；
Due to constitute role each limb member can by multiple limb member models, as needed select
Suitable limb member model, forms role.
Three, character pose is put and marks in different time points, to express the requirement of character pose.
In order to facilitate role's posture of expression different time points, this method expresses posture using the method that Matchstick Men is marked
It is required that have different schematic components indicate the number of people, left upper arm, left forearm, left hand, right upper arm, right forearm, the right hand, upper trunk,
Lower trunk, left thigh, left leg, left foot, right thigh, right leg, right crus of diaphragm are well placed each schematic components, and mark its number of people
It turns to, the steering of mouth control expression, eye control expression, right-hand man's formula and trunk, the schematic components being well placed (constituting role framework) table
Up to the requirement of role's posture, and the requirement of the main expression role's expression in part is marked, thus by role's Gesture and role's table
Feelings require to be combined that complete role's Gesture can be expressed.Wherein, express the steering of a number of people, mouth control expression,
The steering of eye control expression, right-hand man's formula and trunk, can be expressed, it is also possible to which the playback head of schematic components is expressed with numeric literal.
It should be noted that avoid limb member modelling and role from the repetition of work such as making, first three step can be with
Any step is started, for example, the requirement of character pose can be expressed first, then designs the limb member mould of each limb member
The basic internal state of type and each limb member model, then wherein suitable limb member model group is chosen into role.
Four, it is required according to character pose, the limbs for choosing each limb member are presented, and the limbs of each limb member are presented
It requires corresponding time point to be put in character pose, while role corresponding with character pose requirement is marked at each time point
Expression, character pose include that the expression of role and posture are presented.
Structure is presented in the limbs that several limb members by forming role are presented in the posture of one role at some time point
It is that each limb member exists to be rendered as each limb member outer trace at the time point and external morphology, outer trace at, limbs
The time point corresponding coordinate, size and angle.The external morphology of each limb member is from its corresponding limb member model
External morphology in choose, by orderly changing mutual conversion between any two external morphology in limb member model, wherein
The change shape that the two is formed in mutual transfer process also constitutes the external morphology of the limb member model.
The method chosen from the external morphology in its corresponding limb member model from the external morphology of each limb member
It is：If the external morphology for choosing limb member is the basic external morphology of limb member model, it is basic directly to choose this
External morphology then passing through two conversely, when the external morphology that choose limb member is not belonging to a kind of in basic external morphology
It is chosen in multiple change shapes that the orderly variation pattern of basic external morphology generates.
Such as the internal state of upper limb element is chosen, then first find out upper limb mould corresponding with the upper limb element
Type, it is assumed that the upper limb model include the angle that is formed between its forearm and ancon be in respectively 0 °, 45 °, 90 °, 135 °, 180 ° and
The basic external morphologies such as 270 °, and if the external morphology that choose upper limb element is forearm and the external morphology that hand is in 45 °
When, then directly chosen from the basic external morphology of upper limb model, if to choose upper limb element external morphology be forearm with
When hand is 70 ° of external morphology, then just need first to choose the basic external morphology of 45 ° and 90 ° of upper limb model, then should
45 ° and 90 ° of basic external morphology carries out orderly variation and forms change shape between the two, finally in these change shapes
Find internal state of the forearm with hand in the change shape of 70 ° (or close to 70 °) as the upper limb element to be chosen.
Similarly, limbs presentation of each limb member on any two time point can also orderly change phase by color lump
Mutually conversion, the two intermediate change limbs are presented to be made of the variation of the track linear change and external morphology of each limb member.Limbs
The orderly variation of element is similar with the orderly variation of limb member model, in fact, the external morphology of limb member is limbs
One kind in component models in complete external morphology, therefore, the orderly variation in the present invention can be understood as in external morphology
The orderly variation of color lump, in other words, orderly variation is to generate suitable limbs to realize to the external morphology of limb member model
The external morphology (more specifically referring to the external morphology that limb member is presented) of element, and having for external morphology is presented in each limb member
Sequence variation is that the character pose in different time points links up, and forms the consecutive variations of character pose.
Therefore, two time points upper corresponding limb member external morphology and external morphology variation have multilayer color lump
It is superimposed to be formed with subcomponent, has on every layer and only there are one color lump or subcomponents, each limb member is on any two time point
Limbs be presented by orderly variation mutually conversion meet：
Equivalent layer between two time points upper corresponding limb member external morphology and the external morphology variation of the two
It is color lump or subcomponent；
If the equivalent layer is color lump, the node total number all same of the color lump in equivalent layer, and between node one by one
It is corresponding.
Five, it is presented by orderly changing the limbs of each limb member between generating arbitrary two adjacent angulars color posture, composition
The consecutive variations of role's posture, and because each time point be labeled with corresponding role's expression, therefore, role's posture it is continuous
The combination of variation and role's expression, completes the consecutive variations of character pose, finally carries out flash demo by playback head, that is, complete whole
A cartoon making.
Six, addition attachment (optional step)
Hand-held stage property, garment trim and other items are considered as attachment by system, certain point (being typically deformation point) of attachment
Deformation trace tracks the topology location of the color lump in limb member model internal state or the relative position of subcomponent.Adhere to matter-element
The interior change of part is generated according to the pace of change of its track, to generate the effect waved or shaken.
For example：
Assuming that using the animation process that the step one in above-described embodiment is illustrated to five as this, then：
First, it is assumed that the limb member of composition role is made of six part limb member B, C, D, E, F, G, each limb is designed
The limb member model of volume elements part, for example, each limb member is there are three limb member model, (limb member B is by limbs member
Part Model B 1, B2, B3 composition), basic external morphology design, such as limb member are carried out to these different limb member models
The basic external morphology of Model B 1 is made of external morphology B11, B12, B13.
Secondly, suitable limb member model is selected, role is formed, for example, as needed, the limbs member of composition role A1
Part model has B1, C1, D1, E1, F1 and G1, it can thus be seen that the combination of different limb member models, may be implemented different
Role, role's diversification, then because these limb member models are design in advance, therefore, there is no need to repeated labor.
Again, character pose is put and marks in Each point in time by schematic components, to express in each time point
Character pose requirement, this step design so that more easily and conveniently to the operation of next step.
Then, according to the character pose requirement expressed in Each point in time, each limbs are presented to the role's posture constituted
It is put, meanwhile, mark corresponding role's expression.Because limbs presentation is made of external morphology and formalness, and external
Form is only the linear change of each limb member corresponding coordinate, size and angle in different time points, more simple when putting
Single, therefore, the external morphology for only illustrating limb member is presented in limb member here.For example, angles of the role A1 on time point X
The posture of color is rendered as A11, and role's expression is H1, then choosing corresponding external morphology, limbs from the presentation of each limbs first
It is to be chosen from the external morphology of limb member model, such as the limbs of limb member B to be selected to be rendered as BN1 (limbs to present again
The external morphology of volume elements part B), if one kind that BN1 is exactly the basic external morphology for limb member Model B 1 is presented in limbs,
Then directly choose (such as basic external morphology B11)；Selecting the limbs of limb member C to be rendered as CN1, (limb member C's is interior
Portion's form), if one kind that CN1 is not the basic external morphology for limb member MODEL C 1 is presented in limbs, first to limbs member
The basic external morphology of part MODEL C 1 is (with the inside substantially of two limb member MODEL Cs 1 being connected before and after limbs presentation CN1
Form) orderly changed, multiple change shapes are generated, are chosen from these change shapes, for example, limbs presentation CN1 is final
For the change shape C111 that the basic external morphology C11 and C12 of limb member MODEL C 1 are generated, other selection modes are similar, most
Eventually, the posture of roles of the role A1 on time point X be rendered as A11 be basic external morphology B11, it is change shape C111, basic
Role's posture that external morphology D11, change shape E111, basic external morphology F11, change shape G111 groups are shaped as, then add
On be labeled in role expression F1 on time point X, form the character pose on time point X；Similarly to being carried out in other times
Process is put in similar operation completion, and in the process, the internal state that mainly limbs are presented chooses process.
Finally, by orderly being changed to Each point in time (mainly adjacent any two time point), here
Orderly the orderly variation of the color lump in external morphology is presented in the mainly each limbs of variation so that character pose connects on a timeline
Continuous distribution, then control broadcasting is carried out by playback head, complete the manufacturing process of entire animation.Certainly, can also have one as needed
The operation of a little attachments.
From the above citing and attached drawing 6 it is found that the data or flow of the animation process of the present invention have distinct level knot
Structure, by limb member model → role → role's posture, and when we design, it is only necessary to make the limbs member of each limb member
Several basic external morphologies of part model and each limb member model can form different roles by different combinations
And role's posture is presented.
Above-described embodiment simply to illustrate that the present invention technical concepts and features, it is in the art the purpose is to be to allow
Those of ordinary skill cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all
It is the equivalent changes or modifications made according to the essence of the content of present invention, should all covers within the scope of the present invention.
