Expand description
Spatial indexing.
An R-tree over element bounds, used for picking, selection-by-region, section boxes, and
the broad phase of clash detection (docs/ifc-semantics.md §4.2, §11 Phase 5).
Bulk-loaded and rebuilt rather than updated in place. A stale index silently returns wrong answers, which is a far worse failure mode than the cost of a rebuild.
Structs§
