Path-tracing in BabylonJS

[JohnK]

@erichlof

And as you also know, rendering any significant amount of triangles is very expensive and without a BVH, it becomes non-real time very quickly.

I have been looking at BVH for Babylon.js Bounding volume hierarchies (BVH) for ray tracing with Morton Codes

@erichlof is this of use in producing an optimised official version in Babylon.js or do you already have code for this?
