00020
00021 RT_GRID_CACHE cache grid hits
00022 RT_TRI_CACHE cache triangle intersections
00023
00024 RT_GRID_SHADE_DEBUG set tri id to intersection level
00025 RT_MEM_DEFRAG allocate small chunks of memory
00026 RT_SUPPORT_GENS support general objects (not just tris)
00027 RT_VIS include visualisation stuff for drawing the grid
00028 USE_ANSI_C use C rather than C++ mem operations
