Description
Technical field
The present invention relates to computer graphics, particularly relate to a kind of method for making of multi-point touch 2 D animation.
Background technology
Animation as a kind of comprehensive art merging numerous artistic class, from from it is born just with the form of expression of himself uniqueness and the using value woods independent of world's art.The high speed development of computer graphics and hardware technology makes computer animation start to move towards brilliant.The primo such as " Star War ", " Toy Story ", " Jurassic Park " allows people have one's quantum of the glamour of Computer Animated Graph.Computer animation has penetrated into each corner of people's life, is widely used in the various fields such as commercial advertisement, television film leader, film and television stunt, cartoon, game, education, military affairs.The manufacturing technology of computer animation has a lot, typical in key-frame animation, animation, human body animation and physically-based animation etc.Wherein, key-frame animation is a kind of technology the most classical.The concept source of key frame makes in traditional cartoon.The make-up room of WaltDisney in early days, the key picture (i.e. so-called key frame) during skilled animation teacher is responsible for designing cartoons, then designs intermediate frame by general animation teacher.In graphics field, scholars are devoted to study the various various technology generating two kinds of frames for convenient and high-quality: conveniently artist's design key frame, researchist proposes various deformation technology.Their basic thought comparatively simply acts on behalf of handle by editor exactly, and the transform effect acting on behalf of handle is delivered on whole complex object in a natural manner, thus the entirety editor realized object, key problem here how the conversion acting on behalf of handle to be delivered in a natural manner on whole object.Some researchists adopt the method based on grid, the people such as Igarashi
[1]devise the analytical algorithm of a substep, first determine each leg-of-mutton suitable rotation on triangle gridding according to handle conversion, and then adjust their scaling further.Two steps all with the optimization being expressed as second energy, thus are converted into the Solve problems of a linear system by them, reach in real time.Sheffer and Kraevoy
[2]and the people such as Sorkine
[3]there is the coordinate of specific invariable attribute to catch the local shape of triangle gridding by introducing, in deformation process, keep these coordinates constant thus the local shape of triangle gridding is kept.Some researchists are also had to propose various non-mesh method, the Free Transform technology that Sederberg and Parry proposes
[4]and the thin plate spline deformation technology that Bookstein proposes
[5]be some early stage examples, follow-up researchist devises the generalized barycenter coordinate of various shape sensitive, such as HCCI combustion
[6,7]and their various improved forms
[8,9,10]; For intermediate frame, because in whole animation sequence, role is different, be all generally by carrying out automatic interpolation generation to two key frames.Selecting which type of geometric sense to carry out interpolation is key problem wherein.Fairly simple method carries out a linear interpolation to each corresponding point, but this mode easily causes the problems such as contraction.The people such as Xu
[11]the deformation gradient of diabolo carries out linear interpolation, and rebuilds the apex coordinate after interpolation eventually through solving Poisson equation, but the method there will be flaw when speed ratio is larger.The people such as Winkler
[12]the mode adopting the length of side of diabolo and dihedral angle to carry out non-linear interpolation solves the large problem rotated, but the method is very consuming time.Fr ¨ ohlich and Botsch
[13]propose one approximation method fast.
Although the relative production technology of 2 D animation obtains discussing lastingly and widely in figure educational circles, but it is pointed out that existing research more concentrates on and how to improve in the effect of animation.The interactive interface of existing animation system still more complicated and abstract, especially amateurish fan is not suitable for: (1) is although as long as the progress of deformation technology allows artist just can realize the natural deformation to object entirety by some simple handles of editor, thus design high-quality key frame, but the degree of freedom of these handles remains higher, and some editing operation such as rotation etc. adopts mouse mode still to seem directly perceived not; (2) mode that existing animation system mostly provide only timeline allows the time course of artist to animation sequence control, realize F.F. to go out soon or slow-motion such as to go out slowly at the effect, such mode of operation seems particularly abstract, and the obvious limitation of the edit format of this one dimension is also very large.

1. handle is specified
User can specify various editor's handle by the handler definition gesture (Fig. 4) of design, user can defining point, limit, lines and region handle.
2. animation producing
User can by the handle editor gesture (Fig. 5) of design to handle
position, direction etc. effectively edit.An edited result affined transformation T of each handle

Finally, QUADRATIC PROGRAMMING METHOD FOR is adopted to carry out solving the weight distribution function that can obtain each handle.
For intermediate frame, obtain by carrying out non-linear interpolation to key frame at the whole story.For each triangle of beginning key frame triangle gridding
and at the corresponding triangle of last key frame
the mapping A between them can be constructed

4. signal edit
After completing the signal decomposition to animation sequence, just very intuitively can edit three signals respectively, thus effectively edit whole animation sequence.
(1) localize time domain editor
Owing to have employed the B-spline curves of local support to represent time-domain signal f, this allows can edit time-domain curve by the control vertex editing B-spline curves easily, and these editors will only have influence on some adjacent frames.In addition, due to postural cue
flatness guarantee that such editor can not cause the jump of grid sequence to change.Multiple control vertex can be edited by the mode of multi-point touch simultaneously.
(2) resampling
New postural position can also be obtained by carrying out resampling to time-domain curve, and then obtain one group of new Deformation Series.
(3) shape territory editor
By the editor to shape territory, animation process can be moved to another grid sequence from a grid sequence.
(4) posture territory editor
A dynamic grid sequence can be generated with growing out of nothing by the editor in posture territory.
The invention discloses a kind of multi-point touch control type two-dimension cartoon making and edit methods, comprise the following steps: 1) handle is specified: user adopts handler definition gesture to specify various types of handle over an input image; 2) animation producing: to specify handle for constraint structure triangle gridding, calculate each handle conversion weight.User handles each handle of gesture editing by handle, according to the position after each vertex edit of Transformation Weight re-computation grid, upgrades the image embedding grid finally by barycentric coordinates interpolation; 3) signal decomposition: the animation that dynamic triangle gridding sequence represents is resolved into shape, posture and time three relatively independent signals; 4) signal edit: user can be individually-edited to isolated several signal respectively by the multi-point touch gesture of good definition; 5) animation exports: call storehouse and animation sequence is stored as the output of GIF picture.
