Abstract
The invention relates to a method for caching point data for three-dimensional animation software. The method includes the following steps that (1) a CPU reads scene files from a hard disk, conducts scanning classification processing on the scene files and outputs processed data to a data temporary storage; (2) the CPU extracts data required in a scene from the data being scanned and classified and outputs the data to the data temporary storage; (3) a GPU extracts the processed data in the step (2) and processed data in the step (1) from the data temporary storage and reconstructs the whole scene. Compared with the prior art, the method has the advantages of effectively reducing system loads for reconstructing the scene and effectively solving the material problem in the scene.

232) the world coordinates present frame matrix data with all animation displacement objects stores in the data working storage;
233) the world coordinates data of having a few with all animation changing objects store in the data working storage.
Described GPU is extraction step 2 from the data working storage) data and step 1 after processing) data after processing, rebuild whole scene and be specially:
31) read in step 1) data after processing
32) according to hiding attribute information, reject hidden objects;
33) according to the object tabulation in upper two steps, for the displacement object, from step 2) take out in turn its corresponding world coordinates matrix data in the data that obtain, wherein directly give the position to static displacement object, to animation displacement object, generate key frame information and node, be connected on each displacement rotating convergent-divergent passage;
34) read all static changing object information, then go out the world coordinates coordinate data of having a few of this static changing object from scene output extracting data, generate single frames object point caching standard formatted file, and be connected on the some Position input passage of object correlation, and adjust setting, so that all work in whole section animation time scope;
35) with step 34), when difference was to process the animation changing object, reading data also generated point cache file frame by frame frame by frame, and connects.
Compared with prior art, the present invention has the following advantages:
Consider from net result, object scene is classified according to its characteristics, so that can guarantee in the process of the whole scene of reconstruct with original scene in the object strict conformance, and reconstruct animation information and point cache out, can both be optimized to limit, effectively reduce the system loading in the reconstruct scene; And because all objects still are objects in the original scene in the reconstruct scene, effectively solve material problem in the scene.
