Description
Technical field
The present invention relates to computer graphics techniques field, more particularly to a kind of rendering intent and of 3D skeleton cartoons
Plant the rendering device of 3D skeleton cartoons.
Background technology
Currently there are two kinds of modes of model animation：Vertex animation and skeleton cartoon.In skeleton cartoon, model has mutual
Connection " bone " composition skeleton structure, by change bone direction and position come be model generate animation.
The skeleton cartoon processor performance higher than vertex animation requirement, but it also has more advantages, bone simultaneously
Animation can be easier, more quickly create.Different skeleton cartoons can be incorporated into together, such as model can be with rotary head
Portion, shooting are while also walking.Some engines can be with the single bone of real time management, thus can be more accurate with environment
Interact --- model can bend and observe or shoot to certain direction, or somewhere pick up one from ground
Thing etc..
At present, general 3D（It is i.e. three-dimensional）All it is that every frame animation uses CPU when skeleton cartoon is realized in engine
（Central Processing Unit, central processing unit）Instant computing overall situation bone matrix data, then submits to GPU again
（Graphics Processing Unit, GPU）, render 3D skeleton cartoons model.However, using above-mentioned
Method realizes 3D skeleton cartoons, and because every frame animation is both needed to consume CPU computing resources, 3D skeleton cartoon model quantity can be led when big
Cause CPU usage too high；It is right especially for some especially consumption CPU come for the skeleton model for calculating bone gesture data
The consumption of cpu resource is even more serious, results even in the appearance for quoting Caton phenomenon.
The content of the invention
Based on this, the present invention provides a kind of rendering intent and device of 3D skeleton cartoons, can reduce the occupancy of CPU,
Reduce the consumption of cpu resource.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of rendering intent of 3D skeleton cartoons, comprises the following steps：
Skeleton cartoon object is created, and loads the global bone matrix data for previously generating；
Be loaded into animation object go forward side by side action picture play, from the global bone matrix data obtain animation present frame institute
The bone matrix data of needs, and by the incoming GPU of the bone matrix data；
Skeleton cartoon shader code, image object and model vertices data are obtained in GPU, and according to acquired
Bone matrix data, skeleton cartoon shader code, image object and model vertices data carry out computing, render bone and move
Drawing face.
A kind of rendering device of 3D skeleton cartoons, including：
Object Creation and data load-on module, for creating skeleton cartoon object, and load the global bone for previously generating
Matrix data；
Data acquisition module, for be loaded into animation object go forward side by side action picture play, from the global bone matrix data
Bone matrix data required for obtaining the present frame of animation, and by the incoming GPU of the bone matrix data；
Rendering module, for obtaining skeleton cartoon shader code, image object and model vertices data in GPU,
And transported according to acquired bone matrix data, skeleton cartoon shader code, image object and model vertices data
Calculate, render skeleton cartoon picture.
By above scheme as can be seen that the rendering intent and device of 3D skeleton cartoons of the invention, before animation broadcasting
Through having previously generated global bone matrix data, global bone square can be so loaded directly into during playing animation
Battle array data, it is no longer necessary to which CPU goes to calculate global bone matrix data of the skeleton cartoon per frame, so as to avoid in actual environment
The cpu resource brought by the global bone matrix data of CPU calculating consumes excessive problem, effectively reduces the occupancy of CPU
Rate, has significant performance advantage especially for the complicated and huge skeleton cartoon model of amount of calculation.
