I can't find the relevant code that initializes the seg_stp. The rt_shot
methods in primitive files simply copy the passed soltab pointer. In
shootray(), this is obtained from a cutter, which is a union for space
partitioning.
My understanding is that the structure soltab keeps track of all the
relevant information pertaining to a solid (primitive). On the GPU side,
only ID (seg_sti) is used. How do I initialize the cpu->seg_stp field?
Thanks,
