Three-dimensional figure data processing method and device

Abstract

The invention provides a three-dimensional figure data processing method and a device. The three-dimensional figure data processing method comprises the steps of acquiring a three-dimensional figure data set comprising a plurality of batches, wherein each batch comprises vertex data of one or a plurality of triangle surfaces; combining the plurality of batches into one or a plurality of combined batches to form an optimized three-dimensional figure data set by adding degraded triangle surfaces; and outputting the optimized three-dimensional figure data set for a figure processor to draw a three-dimensional figure with one whole combined batch used each time.

Description

Technical field [0001] The invention relates to a three-dimensional graphic data method and device. Background technique [0002] The imaging process of real-time three-dimensional (3D) applications often involves rendering various dynamic objects to the screen. Most of the current deformable animation techniques are implemented using skin-bone animation techniques. [0003] The 3D rendering process is generally implemented by a shader (Shader) of a Graphics Processing Unit (GPU). Among them, a three-dimensional vertex shader (Vertex Shader) is used to calculate the animation of the skeleton and the skin. [0004] To use the GPU to make skeletal animation, you need to calculate the degree of influence of the bones on the coordinates of each vertex of the 3D object in the vertex shader. For each 3D vertex coordinate, it is necessary to record which specific bones it will be affected by, and the weight of each bone's influence on the vertex.
