Detailed Description

Cache of dot products of ray origin and direction with the FDH. These products depends only on actual ray but they are FDH-independent. Therefore they can be used to accelerate of FDH-tree traversal. On the other hand, filling the cache makes the first successful ray itersecrion test slower. See the ENV_USE_CACHE option in the PointEnv structure for more details.
