combinedLocalAabb property

Aabb3T? combinedLocalAabb
getter/setter pair

Union of this node's mesh primitive AABBs together with each descendant node's combined_local_aabb transformed by the descendant's local transform. Expressed in this node's local space.

Lets the runtime cull entire subtrees with a single AABB-vs-frustum test instead of recomputing the union every frame. Optional for backwards compatibility.

Implementation

Aabb3T? combinedLocalAabb;
