Data Optimization for 3D Model Rendering by Triangle Strip Deriving

GPU vertex cache hit rate has a significant impact on 3D rendering performance,and the model data organization is the most important factor for the vertex cache hit rate.In this paper,we present a new mesh optimization method.By checking up the problems in vertex cache missing,we setup a Seed Strip in the model mesh,and select the vertices associated with multiple edges in the Seed Strip to form a new strip called Derived Strip.Through the establishment of the Seed Strip and Derived Strip repeatedly,we generate an optimized triangle sequence of the model mesh which can be used to raise the GPU vertex cache hit rate as well as the rendering performance.
