gather density error #58

The example runs correctly on my machine. So I tried to use my own point cloud data with the point cloud example. Does anyone know how to solve the issue?

  1. configure GVDB
  2. allocate point cloud on GPU
  3. use SetDataGPU and setPoints to hook up the data
  4. launch my own kernel that generates a new point cloud to the allocated GPU memory
  5. and then finally calls update: image

I am missing something important. I'd appreciated if someone can point it out.

I also tried "GatherLevelSet". But it is the same issue. What restricts/assumption do I need to know for the point cloud input?
