Detailed Description

Structures for space subdivision.

RT_PART_NUBSPT uses CUT_CUTNODE interior nodes and CUT_BOXNODE leaves. RT_PART_NULL intentionally uses one CUT_BOXNODE leaf covering the whole model so the ray shooting path can evaluate a no-op spatial partitioning baseline without a separate primitive-list traversal.

cut_type is an integer for efficiency of access in rt_shootray() on non-word addressing machines.

If a solid has 'pieces', it will be listed either in bn_list (initially), or in bn_piecelist, but not both.
