Has anyone successfully implemented an Octree using D3DXSplitMesh or is everyone else better off splitting the mesh manually? The problem is sometimes a single split mesh would result in having vertices completely far away or at opposite end of each other. If D3DXSplitMesh would split the mesh by bounding boxes side by side then putting the meshes in an octree would be a trivial unfortunately not. Thanks in advance for any insights.

Quick glance at the docs indicates this is only a numerical split, not a spatial one. What is the application here? Terrain?

Hi Dave

Thanks for your reply.

Not for a terrain but for a complete mesh level - castles, fortress, dungeons etc.,
