Detailed Description

A convex volume defined by bounding planes (for ramps, angled walls, etc.).

The solid interior is the intersection of all half-spaces: dot(normal, p) < distance. Normals point outward (into free space), same as the Plane convention.

k_maxPlanes is sized to fit the typical output of V-HACD convex decomposition: each output hull has up to ~64 vertices (the V-HACD m_maxNumVerticesPerCH parameter we pass), and a triangulated convex polytope's face-plane count is bounded by ~2V-4 for V vertices but in practice (after coplanar-triangle deduplication) much lower. 64 planes is comfortable headroom and keeps each WorldBrush at 1KB — well within L1 cache for the per-frame collision loop.
