is it possible to combine it with a mesh rendering? So a plan (mesh) and real (pointcloud) comparison is possible
current workaround (not tested)
see BinaryViewerDX11.cs, around line "Debug.Log("Building octree...");",
just collect all meshes that you need, add their vertex points to that pointTree list and test..
for later updates i'm thinking something like:
- AddPoints() to add any array of points to current octree
- RemovePoints()
