Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/BulletCollision/OptimizedBvhNode.cs

A small data container class representing a node in an optimized bounding volume hierarchy (BVH) used by the Bullet collision code. It stores AABB min/max as IndexedVector3 and indices used for traversal (escape index, subpart, triangle index).
