Shown in Figure 1, a kind of rendering intent of cartoon scene provided in an embodiment of the present invention includes the following steps：

S101 obtains the changing coordinates of role in cartoon scene；

Optionally, S101 steps can obtain or obtain the changing coordinates of role in cartoon scene.

May include one or more roles in cartoon scene, role can be a cartoon character or figure image, For each role in cartoon scene, changing coordinates of the role in cartoon scene can be obtained, for a certain role For, the changing coordinates of the role can be：Before the step of executing the outpost of the tax office in selection role's visual range region, the angle Color coordinate residing in cartoon scene.When selecting the outpost of the tax office in role's visual range region, need first to transfer angle The changing coordinates of color determine the visual range region of role according to present coordinate values.

In a kind of realization method, screen coordinate system can be established based on cartoon scene, it is thus possible to obtain the geometry of role Changing coordinates of the central point under screen coordinate system, the changing coordinates as role in cartoon scene.In other modes, also may be used With the changing coordinates by role's body some location point under screen coordinate system, the changing coordinates as role in cartoon scene.

S102 selects the outpost of the tax office in the first predeterminable area centered on the changing coordinates of role, is closed as each target Card；

Wherein, it is preset role's visual range region in the first predeterminable area.

Optionally, S201 steps can be all in the first predeterminable area selected centered on the changing coordinates of role The outpost of the tax office, as each target outpost of the tax office.

Different types of object can be distributed in each region in cartoon scene, and object can be divided into building, vegetation, stone Head, lawn etc., building may include house, enclosure wall, barrier etc..In general, object it is irregular be distributed in each region, example Such as, some regional simulation Urban Distributions may include densely distributed building, some regional simulation depopulated zones can only include Large stretch of meadow.The objects of object or different closenesses to different complexities are loaded, unloaded and are rendered, required consumption Physical memory, GPU (Graphics Processing Unit, graphics processor) be different, what building was more concentrated The required physical memory in region, GPU are larger, therefore the region can be defined as to an outpost of the tax office, without the region of building Physical memory, the GPU of required consumption are smaller, can be ignored for the region of not building, and it is the non-outpost of the tax office to think it.In That entire cartoon scene is divided into outpost of the tax office region and non-outpost of the tax office region, be distributed with one by one it is of different sizes, shape is different, area Some outposts of the tax office different, position is different, these outposts of the tax office can be juxtaposition.

It is understood that different threads can be run in GPU, such as load thread, unloading thread and rendering thread, It is frequent to carry out load thread, unloading thread and render thread, but the performance consumption of GPU can be caused larger.Although by dynamic The mode that picture scene partitioning goes out the different outposts of the tax office optimizes load link, but if together by the outpost of the tax office of whole cartoon scene It is loaded into GPU, although future will be facilitated to be rendered at any time, GPU consumption can be caused larger.Cartoon scene is bigger, including The outpost of the tax office it is more, especially play when just starting, the outpost of the tax office of whole cartoon scene is all if load, it is still desirable to Yong Huhua The longer load for falling into a long wait game can be lost in a large amount of clients in this waiting time.If cartoon scene is sizable If map, whole outposts of the tax office, which all load, becomes unrealistic, and therefore, as a specific embodiment, we choose a part of pass Block the mode that is loaded to handle.

Each outpost of the tax office can be a rectangular region, can also be the border circular areas around some central point, also may be used To be the region of irregular shape.The area and shape at the different outposts of the tax office can be different.The region that the different outposts of the tax office are covered it Between can have overlapping region.As the specific embodiment of the present invention, it is distributed with if attached drawing 2 is shown in a map scene A dry outpost of the tax office, each outpost of the tax office is rectangular, and the area at each outpost of the tax office can be different, can also be identical, the different outposts of the tax office it Between may exist overlapping region.

Role's visual range region refers to the region formed by the visual range of role, it is believed that role can see The outpost of the tax office be：All outposts of the tax office in the first predeterminable area centered on the changing coordinates of role, due to role's visual range area Domain is preset, and is fixed once being set size, therefore, the first predeterminable area memory centered on the changing coordinates of role The outpost of the tax office limited amount, i.e. the limited amount at the target outpost of the tax office, typically 3,4,5,6,7 etc..

For the loading method at the outpost of the tax office, we can be in the first predeterminable area centered on the changing coordinates of role All outposts of the tax office are loaded；Can also be the part outpost of the tax office after following some Rules Filtering, i.e., in being with the changing coordinates of role The part outpost of the tax office in first predeterminable area of the heart is loaded.

The present invention does not limit the mode at the selection target outpost of the tax office, for example, a specific embodiment as the present invention, it can The outpost of the tax office to be regarded as to the rectangular area for surrounding multiple buildings, in a kind of realization method, the rectangular area where the outpost of the tax office is fallen completely When entering in the first predeterminable area centered on the changing coordinates of role, the outpost of the tax office can be selected as the target outpost of the tax office.

It is understood that the rectangular area where the outpost of the tax office falls into the first preset areas centered on the changing coordinates of role Region in domain is：Weight between rectangular area where the outpost of the tax office and the first predeterminable area centered on the changing coordinates of role The area in folded region, the first predeterminable area can be more than/being equal to/less than the area of rectangular area where the outpost of the tax office, when the overlay region When the area in domain is equal to the area of smaller area, it is believed that rectangular area where the outpost of the tax office falls completely within the changing coordinates with role Centered on the first predeterminable area in；When the area of overlapping is more than zero and is less than the area of smaller area, it is believed that the outpost of the tax office Place rectangular area part is fallen into the first predeterminable area centered on the changing coordinates of role, and smaller area can be：It closes Smaller between rectangular area where card and the first predeterminable area centered on the changing coordinates of role.

For example, smaller area can be：Rectangular area where the outpost of the tax office, and the area of smaller area is 10 square centimeters, when The area of overlapping region between rectangular area where the outpost of the tax office and the first predeterminable area centered on the changing coordinates of role When being 10 square centimeters, it is believed that rectangular area where the outpost of the tax office is fallen completely within centered on the changing coordinates of role first pre- If in region；When the rectangular area where the outpost of the tax office and overlapping between the first predeterminable area centered on the changing coordinates of role When partial area is 5 square centimeters, it is believed that rectangular area part where the outpost of the tax office falls into is with the changing coordinates of role In first predeterminable area of the heart.

Alternatively, in another realization method, when where the outpost of the tax office rectangular area with centered on the changing coordinates of role When the area of overlapping region between first predeterminable area is more than the preset multiple of rectangular area area where the outpost of the tax office, it can select The outpost of the tax office can be previously set as the target outpost of the tax office, preset multiple according to user demand, and it is not limited in the embodiment of the present invention, For example, can be 1/2,3/4,4/5 etc..

For example, preset multiple is 1/2, the rectangular area where the outpost of the tax office and first centered on the changing coordinates of role are pre- If the area of the overlapping region between region is 10 square centimeters, the area of rectangular area where the outpost of the tax office is 15 square centimeters, then The outpost of the tax office can be selected as the target outpost of the tax office.

In another realization method, it is with the changing coordinates of role when the central point of the rectangular area where the outpost of the tax office is fallen into When in first predeterminable area at center, the outpost of the tax office can be selected as the target outpost of the tax office.

In special circumstances, role is located just at the region of multiple outpost of the tax office overlappings, such as the present co-ordinate position residing for role, It falls into the regional extent at 2 or 3 outposts of the tax office.Have one when the rectangular area where the outpost of the tax office as a specific embodiment When part is fallen into the first predeterminable area, the outpost of the tax office can be selected as the target outpost of the tax office.Such as when the rectangular area where the outpost of the tax office When the 1/3 of area is fallen into the first predeterminable area centered on the changing coordinates of role, the outpost of the tax office can be selected as target The outpost of the tax office；When the coordinate of the rectangular area periphery length of side where the outpost of the tax office, fall into first default centered on the changing coordinates of role When in region, the outpost of the tax office can be selected as the target outpost of the tax office.As a specific embodiment, when the rectangular area where the outpost of the tax office Central point when falling into the first predeterminable area centered on the changing coordinates of role, the outpost of the tax office can be selected to be closed as target Card.

S103 renders the object in each target outpost of the tax office, obtains the rendered picture of role.

Object in the outpost of the tax office may include vegetation (for example, trees, flowering shrubs, thick grass etc.), building, stone and lake etc. Deng.It is understood that before not rendered, each object in the outpost of the tax office exists in the form of dummy model, after rendering, Each object exists in a graphical form, in turn, can obtain the rendered picture being made of each figure.

Specifically, in cartoon scene can there are one or multiple roles LOD may be used for each role (Levels of Detail, detail) Rendering, renders the object in each target outpost of the tax office, so as to Obtain the rendered picture of the role.

Behind the outpost of the tax office in the first predeterminable area centered on selection is by the changing coordinates of role, that is, the target outpost of the tax office is selected Afterwards, it can first determine the overlapping region between each target outpost of the tax office, the object in identified each overlapping region be carried out primary It renders, rendering can be repeated to avoid the object between the different outposts of the tax office in overlapping region, then render the non-heavy of each target outpost of the tax office Object in folded region, the embodiment of the present invention do not limit rendering order, in other embodiments, can also first render each Object in the Non-overlapping Domain at the target outpost of the tax office, then render the object of the overlapping region between each target outpost of the tax office.

Optionally, S103 steps can be rendered to the object in each target outpost of the tax office, obtain or obtain role Rendered picture.

As it can be seen that using technical solution provided in an embodiment of the present invention, some target outposts of the tax office are picked out from cartoon scene, By the load or unload of each target outpost of the tax office, rather than all outposts of the tax office in cartoon scene are loaded, unloaded and rendered, it will Reduce the consumption to GPU, CPU, memory.It is related without rendering during carrying out animation rendering to the first predeterminable area Card, only renders the object in each target outpost of the tax office, to improve the efficiency of animation rendering.

Specifically, for the object in the target outpost of the tax office, in order to further increase rendering efficiency, in each target outpost of the tax office Object is rendered, and may comprise steps of：

Obtain the coordinate of each similar object in all target outposts of the tax office；

Similar object is rendered at the coordinate of each similar object.

Wherein, each similar object is：Belong to each object of same default object type.

For convenience of description, a specific embodiment as the present invention, it is assumed that object is vegetation, and object type is vegetation Type.

Vegetation pattern can be divided into the thick classes such as draft class, shrub and arbor class, can also be divided by plantation varieties：Osmanthus Subclasses, each vegetation pattern such as flower tree class, apricot flower tree class, flowering cherry class, sensitive plant class can pre-set a vegetation pattern Mark is identical to be identified whether according to vegetation pattern, it may be determined that whether vegetation belongs to same vegetation pattern, certainly, also may be used A vegetation characteristics value is pre-set with each vegetation pattern, it is thus possible to it is whether identical according to vegetation characteristics value, determine vegetation Whether belong to same vegetation pattern, specific vegetation pattern and determine whether vegetation belongs to the mode of same vegetation pattern can be with It is pre-designed according to designer's demand, is not limited herein.

In one embodiment, the coordinate of each vegetation and vegetation pattern parameter can correspond in advance is stored in data Library can obtain the coordinate of each similar vegetation in all target outposts of the tax office, vegetation pattern parameter by reading database in turn It can be the parameter that vegetation pattern mark or vegetation characteristics value etc. are used for unique mark vegetation.Vegetation characteristics value can be according to plant Each numerical parameter of the different attribute label of object, can be divided into the parameter of many classifications, can be arbor or shrub, be temperature Band plant or tropical plants, be yellow blade or green blade, be deciduous plant or aithullium etc., computer according to The characteristic value of plant renders specific plant shape.

The coordinate of vegetation can be coordinate of the geometric center point under screen coordinate system of vegetation, or vegetation some Coordinate of the location point under screen coordinate system.

When rendering vegetation, in all target outposts of the tax office of acquisition after the coordinate of each similar vegetation, it can only pass through one Render request renders similar vegetation at the coordinate of each similar vegetation, this sends out time of render request by saving to GPU Number.

For example, vegetation pattern includes sensitive plant class and osmanthus fragrans class, the geometric center point of sensitive plant is under screen coordinate system Coordinate be respectively a1 and a2, the coordinate of the geometric center points of osmanthus fragrans under screen coordinate system is respectively b1 and b2, then is sitting Mark a1 at a2 synchronize render sensitive plant, at coordinate b1 with b2 synchronize render osmanthus fragrans.The concrete numerical value of a1 can be (21,24,33), x-axis component, y-axis component and z-axis component phases of each component value difference denotation coordination a1 under screen coordinate system Distance for coordinate origin is respectively：21,24 and 33 unit values.The description of a2, b1 and b2 can be identical as a1, herein not It repeats again.

In addition, in other embodiments, can also be rendered in the following ways to vegetation：

Obtain the coordinate of the total and each similar vegetation of similar vegetation in all target outposts of the tax office；

A similar plant rendered is arranged in the similar vegetation for once rendering total strain at the coordinate of each similar vegetation Quilt.

The vegetation sum of each vegetation pattern, the coordinate of each vegetation and vegetation pattern parameter can correspond to storage in advance In database, in turn, the total and each same of similar vegetation in all target outposts of the tax office can be obtained by reading database The coordinate of class vegetation.

For example, the vegetation sum that vegetation pattern is sensitive plant is：2 plants, the geometric center point of vegetation is under screen coordinate system Coordinate be respectively a1 and a2, then once render two plants of sensitive plants, and be respectively set one at coordinate a1 and a2 and rendered Sensitive plant.

It should be noted that the embodiment of the present invention is illustrated so that object is vegetation as an example, only of the invention one tool Body example, can be with the above-mentioned rendering mode to plant to the rendering mode of other objects (for example, building, stone and lake etc.) Identical, this is no longer going to repeat them.

By sending render request to GPU (Graphics Processing Unit, graphics processor), wash with watercolours may be implemented Object is contaminated, using the embodiment of the present invention, multiple similar objects that a render request can render are asked compared to primary rendering Seek the method that can only render an object, it is possible to reduce the number that render request is sent to GPU, to improve rendering efficiency.

In order to further increase rendering efficiency, referring to Fig. 3, on the basis of embodiment illustrated in fig. 3 embodiment shown in Fig. 1, After S102, method can also include：

S104, the object for meeting default rejecting rule is rejected out of each the target outpost of the tax office；

As the specific embodiment of the present invention, there is the case where overlapping region in the region where the target outpost of the tax office between each other Under, when counting object in all these target outposts of the tax office, it may appear that object is repeated the risk of calculating, therefore deletes repetition in advance Object can save the time that calculation step is consumed below.Therefore, it is rejected out of each the target outpost of the tax office and meets default rejecting rule Object before, further include step：Object in each target outpost of the tax office is counted, and deletes the object of repetition.So from The step of meeting the default object for rejecting rule is rejected in each target outpost of the tax office, further includes step：Include from each target outpost of the tax office Do not repeat to reject in object and meet the default object for rejecting rule.

In this case, S103 is specifically as follows：

S103A, the object not being removed in each target outpost of the tax office is rendered, obtains the rendered picture of role.

Default rule of rejecting can be previously set according to the demand of designer, and the embodiment of the present invention is to specifically rejecting rule It does not limit then, for example, cone rejecting, occlusion culling and one kind in rejecting or Combination Design rejecting rule can be utilized Then.

Illustratively, it presses distance and rejects design rejecting rule, then rejected out of each the target outpost of the tax office and meet default rejecting rule Object then, may comprise steps of：

Obtain the changing coordinates of the first type objects and the second type objects in the target outpost of the tax office；

Calculate the distance between the changing coordinates of each first type objects and the changing coordinates of role and each second type objects Changing coordinates and role the distance between changing coordinates；

The first distance is rejected in the first preset range and object of the second distance in the second preset range；

Wherein, the first type objects can be：The object for having shielding role effect in all target outposts of the tax office, such as enclosure wall, huge The coordinate of stone and house etc., the first type objects can be：Coordinate of the geometric center point of first type objects under screen coordinate system, Or the coordinate of the first type objects some location points under screen coordinate system.

Second type objects can be：The object for having decoration function in all target outposts of the tax office, such as lamps and lanterns, paster, small decorative article Deng the coordinate of the second type objects can be：Coordinate of the geometric center point of second type objects under screen coordinate system, or Coordinate of some location point of second type objects under screen coordinate system.

Can world coordinate system be established to cartoon scene in advance, and by (including the first type objects of each object in cartoon scene With the second type objects) coordinate under the world coordinate system is stored in database, in turn, can be obtained by reading database each Coordinate of the object under world coordinate system, and coordinate of each object under world coordinate system is converted to the seat under screen coordinate system Mark, so as to obtain coordinate of each object under screen coordinate system, alternatively, directly each object in cartoon scene can also exist Coordinate under screen coordinate system is stored in database, in turn, each object can be obtained by reading database in screen coordinate system Under coordinate.

It should be noted that the dividing mode of the first type objects of the embodiment of the present invention pair and the second type objects does not limit, It is, in different embodiments, specific object can be with the present invention included in the first type objects and the second type objects Embodiment is different, for example, can also be to divide according to size of the object under screen coordinate system in other embodiments Principle divides the first type objects, the second type objects and third type objects etc..

By the way that the object in the outpost of the tax office is divided into the first type objects and the second type objects, multiple congeners can be once rejected Body can improve the efficiency for rejecting object compared to the primary mode for rejecting an object.

First distance can be：The distance between the changing coordinates of first type objects and the changing coordinates of role, second away from From can be：The distance between the changing coordinates of second type objects and the changing coordinates of role.

First preset range and the second preset range can be previously set according to the demand of designer, due to first kind object The volume of body is typically larger than the volume of the second type objects, therefore the starting point of the first preset range can be greater than or equal to the second default model The terminal enclosed.

For example, the first preset range can be [500 ,+∞], [600 ,+∞] or [700 ,+∞] etc., the second default model Enclosing to be：[0,500], [0,300], [50,100] or [50,300] etc., unit can be the list under world coordinate system First preset range and the second preset range can be converted to screen coordinate by position " rice " from world coordinate system in this case Under system, the numerical value of the first preset range and the second preset range under screen coordinate system is obtained, and then whether judges the first distance In the first preset range and whether second distance is in the second preset range.

It, can when the first distance of first type objects is in the first preset range for some first type objects To think：The distance between the changing coordinates of first type objects and the changing coordinates of role farther out, role can not see clearly this One type objects can not have to render first type objects, therefore can reject first type objects；For some second type objects Speech, when the second distance of second type objects is in the second preset range, it is believed that：The changing coordinates of second type objects with Farther out, role can not see second type objects clearly to the distance between changing coordinates of role, can not have to render the second class object Body, therefore second type objects can be rejected.

Using the embodiment of the present invention, the object not being removed in each target outpost of the tax office is rendered, compared to each For the mode that object in the target outpost of the tax office is rendered, it is possible to reduce the physical quantities being rendered are needed, to improve wash with watercolours Contaminate efficiency.

In general, the distance between object and the changing coordinates of role are farther out, then face of the object under screen coordinate system Product is smaller, however, in some cases, although the distance between object and the changing coordinates of role are farther out, object is shielding Area under curtain coordinate system is also very big, for example, area of the building under screen coordinate system is 100 square centimeters, even if in screen The distance between the building and the changing coordinates of role are more than 10 centimetres under coordinate system, and the house is for role, Ke Nengyi It is so visible, it is thus impossible to be rejected.

Alternatively, although the distance between object and the changing coordinates of role are close, object is under screen coordinate system Area also very little, for example, some tiny components (pendant, weapon pendant with such as grass, role), even if in screen coordinate system Lower the distance between the tiny component and changing coordinates are less than 5 centimetres, which may be still not for role It is visible, therefore, it can be rejected.

In conclusion if only rejected according to distance, mistake may be caused, in order to improve the accuracy for rejecting object, In a kind of embodiment, is rejected out of each the target outpost of the tax office and meet the default object for rejecting rule, may comprise steps of：

Step A1, the screen area ratio of each object in each target outpost of the tax office is calculated,

Wherein, the screen area ratio of object indicates the ratio of the area of area and display screen of the object under screen coordinate system Value, display screen are used to show the rendered picture of role；

Step A2, the object that screen area ratio in each target outpost of the tax office is less than default screen area ratio is rejected.

Default screen area ratio can be preset according to the demand of designer, such as can be：2%, 3% or 4% etc..

The area of display screen can be：Area of the display screen under screen coordinate system.

Using the embodiment of the present invention, screen area ratio in each target outpost of the tax office of rejecting is less than default screen area ratio Object avoids rejecting larger object of area under screen coordinate system, and it is smaller to reject the area under screen coordinate system Object, fully considered visibility degree of the object to role, thus improve reject object accuracy,

In a kind of realization method, the screen area ratio of each object in each target outpost of the tax office can be calculated in the following manner Example：

The zoom factor of the first step, the distance and role of calculating object to role's predetermined patterns under current visual angle；

Predetermined patterns can be preset according to the demand of designer, and it is not limited in the embodiment of the present invention, such as Can be eyes, or the position below the role crown at pre-determined distance, alternatively, some position of role's body is default There is virtual camera, in this case, predetermined fraction can be the position residing for virtual camera.

Illustratively, predetermined patterns are eyes, and the distance of object to role's eyes can be：In screen coordinate It is the distance for descending the geometric center point of object to eyes straight line, eyes straight line is：It is linked to be by left eye central point and right eye central point Straight line；Alternatively, the distance of object to role's eyes can also be：The geometric center point of object arrives under screen coordinate system The distance at eyes line segment midpoint, eyes line segment midpoint are：By the midpoint for the line segment that left eye central point and right eye central point are linked to be.

In a kind of realization method, calculating zoom factor of the role under current visual angle can be：Obtain role's current visual angle The number of pixels of the number of pixels of horizontal direction and vertical direction under screen coordinate system, utilizes the picture of obtained horizontal direction The number of pixels of plain number and vertical direction, calculated level zoom factor and vertical scaling factor；By horizontal scaling coefficient and hang down Zoom factor of the greater as role under current visual angle in straight zoom factor.Wherein, the current visual angle of role can recognize It is yes：The field of view formed by the current visual angle range of role.

Wherein, horizontal scaling coefficient can be：Width/2*M[0][0]；Vertical scaling factor can be：Height/2*M [1] [1], Width indicate that the number of pixels of role's current visual angle horizontal direction under screen coordinate system, Height indicate that role works as The number of pixels of preceding visual angle vertical direction under screen coordinate system, M [0] [0] indicate the element value of the 0th row the 0th of projection matrix row, M [1] [1] indicates the element value of the 1st row the 1st of projection matrix row.

Projection matrix can be the matrix of 2 rows 2 row, and projection matrix can be used for each object in cartoon scene from three-dimensional space Between be transformed into two dimensional surface, the specific element size of projection matrix can be previously set according to the demand of designer, the present invention Embodiment does not limit each element size.

Illustratively, Width=10, M [0] [0]=1, Height=10, M [1] [1]=2, horizontal scaling coefficient can be with For：Width/2.0f*M [0] [0]=10/2*1=5, vertical scaling factor can be：Height/2.0f*M [1] [1]=10/ 2*2=10, therefore, zoom factor of the role under current visual angle is：10.2.0f indicating：Data type is single-precision floating point type (float), numerical value 2.0.

Second step, using distance, zoom factor and object the default encirclement radius of a ball, calculate object in screen coordinate system Under encirclement sphere area；

It is understood that for each object in cartoon scene, the model that the object is set, example can be preset Such as, building model and enclosure wall model etc. can be set, and the default encirclement radius of a ball of object can be：Surround object preset model Radius of the sphere under screen coordinate system.The model of object can be threedimensional model,

Illustratively, object preset model is building model, as shown in figure 4, the sphere that Fig. 4 is encirclement building model is shielding Plan view under curtain coordinate system, then the default encirclement radius of a ball of object is 10 centimetres.

Can radius of the sphere that object preset model surrounded under world coordinate system be stored in database in advance, into And radius of the sphere for surrounding object preset model under world coordinate system can be obtained by reading database, and will read To radius screen coordinate system is converted to by world coordinate system, in turn, the default encirclement radius of a ball of object can be obtained；Alternatively, Can radius of the sphere that object preset model surrounded under screen coordinate system be stored in database in advance, in turn, pass through reading Take database that can obtain radius of the sphere for surrounding object preset model under screen coordinate system, the i.e. default encirclement ball of object Radius.

In a kind of realization method, following formula can be utilized to calculate encirclement sphere area of the object under screen coordinate system：

S=π * R*R；R=k/d*r

Wherein, S indicates that encirclement sphere area of the object under screen coordinate system, R indicate that object is worked as in screen coordinate system role The encirclement radius of a ball under preceding visual angle, k indicate that zoom factor of the role under current visual angle, d indicate object to role's predetermined patterns Distance, r indicate object the default encirclement radius of a ball, π indicate pi.As can be seen that encirclement sphere area is：Object is surrounded to exist The area of a circle on screen corresponding to the sphere of shown figure is not the surface area of the sphere.

Illustratively, the default encirclement radius of a ball of object is 2 centimetres, and the distance of object to role's predetermined patterns is 5 centimetres, Zoom factor of the role under current visual angle be 10, then R=10/5*2=4 centimetres, S=π * 4*4.

Third step, the area for obtaining display screen, calculate the ratio for the area for surrounding sphere area and display screen, will calculate gained Screen area ratio of the ratio as object.

Illustratively, the area of display screen is 100 square centimeters, and it is 40 square centimeters to surround sphere area, then the screen of object Curtain area ratio be：The ratio that sphere area accounts for display area is surrounded, as：40/100=0.4.

When role is kept in motion in cartoon scene, the coordinate of role can constantly change, for example, role can be dynamic It draws in scene and is run, upstairs and the movements such as latent.When the changes in coordinates of role is larger, it is believed that role's visual range Region changes greatly, therefore can re-execute render process, when role frequently moves, and role changes in coordinates it is smaller when, It is considered that：Role's visual range region is basically unchanged, in order to avoid frequently executing unnecessary render process.It can no longer weigh It is new to render.

Further, in order to which user can watch rendered picture, after obtaining the rendered picture of role, method can be with Include the following steps：

Step B1, the coordinate of role is detected, and using the coordinate of the role detected as the coordinates of targets of role；

Optionally, can real-time or smaller time compartment of terrain the coordinate of role is detected, obtain the target of role Coordinate value.The coordinates of targets of role can be coordinates of targets of the geometric center point of role under screen coordinate system, or Coordinates of targets of some location point of role under screen coordinate system.

Step B2, calculate role coordinates of targets and role the distance between changing coordinates, as role target away from From；

It is understood that the coordinates of targets of role can be：After obtaining the rendered picture of role, it detected The coordinate of role；The changing coordinates of role can be：Before the selection target outpost of the tax office, role's coordinate for being obtained.Wherein, it detects Mode can be：The mode detected in real time or, detecting primary mode every fixed predetermined period, or often reaches preset time Point detection detects primary mode.

As a specific embodiment the current of role is defined in order to calculate the situation of change of role's coordinate position Coordinate, role coordinates of targets.The time that the changing coordinates of role occur will detect the seat of role earlier than role goal coordinate After scale value, which is recorded as to the changing coordinates of role, continues the coordinate value for detecting role, is then recorded as the mesh of role Coordinate is marked, coordinates of targets and changing coordinates are compared later, the target range of role is calculated.

Step B3, judge whether the target range of role is less than to preset and render distance again；If being less than, then follow the steps B4；

The default distance that renders again can be previously set according to the demand of designer, and the embodiment of the present invention is to presetting again The concrete numerical value for rendering distance does not limit, such as can be：40,50,60,70 etc., unit can be under world coordinate system Unit " rice ", and default will can again render distance and screen coordinate system is converted to by world coordinate system, and then may determine that Whether the target range of role is less than to preset renders distance again.

Step B4, the rendered picture of role is shown.

It is understood that due to being preset role's visual range region in the first predeterminable area, at display angle When the rendered picture of color, Ke Yiwei：It shows corresponding to the object in the first predeterminable area centered on the coordinates of targets of role Rendered picture.Therefore according to the difference of coordinates of targets, the different content in rendered picture can be shown every time.

As can be seen that the default distance that renders again plays the role of buffer strip, preset when the target range of role is less than Again render apart from when, it is believed that for target range within buffer strip range, the moving range of role is smaller, therefore can recognize For the visible object of role is basically unchanged, and can not redefine the target outpost of the tax office, the role obtained before directly displaying Rendered picture, to, user can watch rendered picture.

In a kind of realization method, if the target range of role renders distance again not less than default, method can also include：

Step B5, the coordinates of targets of role is assigned to the changing coordinates of role, return and execute selection with the current of role The outpost of the tax office in the first predeterminable area centered on coordinate, the step of as each target outpost of the tax office (S102).

It is, if target range is default not less than (be more than or be equal to) to render distance again, it may be considered that role Moving range is larger, has exceeded buffer strip range, can redefine the target outpost of the tax office, and then renders to obtain the rendering of role again Picture.

As it can be seen that using technical solution provided in an embodiment of the present invention, if target range renders distance again not less than default, The target outpost of the tax office is then redefined, and then renders to obtain the rendered picture of role again；It is rendered again if target range is less than to preset Distance then shows the rendered picture of role；Therefore, on the basis of ensureing rendered picture reliability, unnecessary wash with watercolours is avoided Number is contaminated, rendering efficiency is further improved.

In a kind of realization method, the outpost of the tax office in the first predeterminable area centered on selection is by the changing coordinates of role is made After each target outpost of the tax office, method can also include：

Each target outpost of the tax office is loaded, and unloads the outpost of the tax office outside the centered on the changing coordinates of role second predeterminable area；Its In, it is the not visible range areas of preset role outside the second predeterminable area；

As the specific embodiment of the present invention, the second predeterminable area is more than the first predeterminable area, presets second area It is equivalent to manufacture with the differently band (region except the first predeterminable area, within the second predeterminable area) of the first predeterminable area One buffer strip, the outpost of the tax office within the buffer strip do not load and unload, and are only carried out to the outpost of the tax office other than the second predeterminable area Unloading.The purpose done so is that role is ceaselessly moving, and after moving interval of time, there are no walk out some targets to close Card appears in first latter two time then for these outposts of the tax office, if the previous time just load, the latter when Between will unload, when then reloading the new target outpost of the tax office again load come up, be not necessarily to, then provided with buffer After band, the outpost of the tax office in buffer strip would not be unloaded.

In this case, the object in each target outpost of the tax office is rendered, is specifically as follows：

The each target outpost of the tax office loaded is rendered.

In a kind of realization method, the step of load thread can be utilized to execute load and the unloading target outpost of the tax office, then, utilize Render the step of thread execution renders each target outpost of the tax office loaded.

Specifically, the first predeterminable area can be：Using the first preset value as the spheric region of radius；Second predeterminable area For：Using the second preset value as the spheric region of radius, the difference of the second preset value and the first preset value can be equal to default wash with watercolours again Contaminate distance.

First preset value and the second preset value can be pre-set according to the demand of designer, such as can be respectively： 400 and 450, unit can be the rice under world coordinate system, can be with when determining the first predeterminable area and the second predeterminable area First preset value and the second preset value are transformed into screen coordinate by world coordinate system.Region between 400 and 450, exactly rises The region acted on to buffer strip.

In other realization methods, the difference of the second preset value and the first preset value can not also be equal to it is default render again away from From default rendering distance again, in addition, the first predeterminable area and the second predeterminable area can be with for example, can be more than or less than For rectangular area, elliptical region, sector region, irregular shape region etc., the first predeterminable area of the embodiment of the present invention pair It is not limited with the shape of the second predeterminable area.Rectangular area calculates more convenient.

All outposts of the tax office in cartoon scene are loaded into the mode of GPU, choosing of the embodiment of the present invention together compared with the prior art The mode that a part of outpost of the tax office is loaded is taken to handle, the load time at the target outpost of the tax office can be shortened, improves loading efficiency.

Further, the step of load and the unloading target outpost of the tax office can be executed using load thread, then, rendering line is utilized The step of Cheng Zhihang renders each target outpost of the tax office loaded improves so as to the less burden for rendering thread Render the execution efficiency of thread.
