BVH_Constants_MaxTreeDepth 

The optimal tree depth. Should be in sync with maximum stack size while traversing the tree - don't pass the trees of greater depth to OCCT algorithms!

BVH_Constants_LeafNodeSizeSingle 

Leaf node size optimal for complex nodes, e.g. for upper-level BVH trees within multi-level structure (nodes point to another BVH trees).

BVH_Constants_LeafNodeSizeAverage 

Average leaf node size (4 primitive per leaf), optimal for average tree nodes.

BVH_Constants_LeafNodeSizeDefault 

Default leaf node size (5 primitives per leaf).

BVH_Constants_LeafNodeSizeSmall 

Leaf node size (8 primitives per leaf), optimal for small tree nodes (e.g. triangles).

BVH_Constants_NbBinsOptimal 

The optimal number of bins for binned builder.

BVH_Constants_NbBinsBest 

The maximum number of bins for binned builder (giving the best traversal time at cost of longer tree construction time).
