It creates a tree cut after knowing that a given point will pass on a BB.
This tree cut is used to accelarate the rays casted from a given BB, eliminating unnecessary BB tests from root till the tree cut.
*Added vbvh - Just a experimental tree type :)
Variable Way BVH - there is no hardcoded number of childs per each Tree Node
- idea is to optimize a tree to reduced the expected number of BB tests even after applying SAH (for that an hardcoded n-way is not enough)
- for now childs are stored on a linked list
to be able to use C++ at raytrace code
C++ used in here is basicly C with templates and function overloads,
to make it easier to reuse code between structures.
For now BVH was converted in C++ and moved to this module
