If you do not care for supporting all sorts of formats, that's what you should probably look up. libMesh, openMesh, CGAL are some C++ based libraries I know of. Most of these libraries will support some sort of mesh import. | |

So I'll have to send the structured data in the form of heap on the GPU and use the traversing scheme on the heap. So wanted to stay away from coding on the cpu side. Anyways thanks for the help, keeping the question open for a little longer in case someone wants to add something. | |

I don't think there is a standard for transforming a mesh to KD-Tree as different implementations have different split heuristics depending on the programmer and application (e.g. Min triangles per leaf / KD-Rope / maximum depth / triangle area based measurement / sparse leaf nodes / etc). | |
