Optimized View Frustum Culling Algorithms for Bounding Boxes

摘要

This paper presents optimizations for faster view frustum culling (VFC) for axis-aligned bounding box(AABB) and oriented bounding box(OBB) hierar- chies. We exploit frame-to-frame coherency by caching and by comparing against precious distances and rotation angles. By using an octant test, we potentially halve the number of plane tests needed, and we also evaluate masking, which is a well-known technique.
