Similar curvature edge collapse simplification based on octree
一种基于八叉剖分的近似曲率的边折叠简化算法*

To improve the speed of triangle mesh simplification, achieve the requirement of real-time display, and reserve more important shape features in the low-level model, the paper presented an improved triangle mesh simplification algorithm. It used octree structure to divide the triangle mesh model into different areas, and then used similar curvature edge-collapse simplification algorithm to simplify each area in parallel. The experimental results show that the improved algorithm obtains a better effect.
