#define ENV_USE_CACHE   (1<<11)

to cache common ray infos Sometimes we can precompute some parts of intersection calculation for some kind of geometry. These precomputed values can be then used to speed up final calculations. For instance, in mohogenous FDH14 tree we can precompute some values that depend on the ray, but do not depend ot the FDH14 themselvs. Because such values are common for tho whole tree, they are computed only one for the tree, stored in the cache and then reused in the final per-FDH intersection calculations. The following variable determines whether to speed up intersection calculations using precomputed cached values. Definition at line 42 of file PointEnv.h.
