class  BVH_LinearBuilder< T, N >
 Performs fast BVH construction using LBVH building approach. Algorithm uses spatial Morton codes to reduce the BVH construction problem to a sorting problem (radix sort – O(N) complexity). This Linear Bounding Volume Hierarchy (LBVH) builder produces BVH trees of lower quality compared to SAH-based BVH builders but it is over an order of magnitude faster (up to 3M triangles per second).

class  BVH::UpdateBoundTask< T, N >

template<class T , int N>
Standard_Integer BVH::UpdateBounds (BVH_Set< T, N > *theSet, BVH_Tree< T, N > *theTree, const Standard_Integer theNode=0)
 Calculates bounding boxes (AABBs) for the given BVH tree. More...
