I have huge point cloud data I want to render them at interactive frame frate. Process I know is

1.point cloud data

2.triangulate it using delnauy or other triangulation algo

3.surface voxelization for mesh

4.volume tracing ti render

But triangulation process is very very slow. Can I somehow voxelize my point cloud directly? I am newbie to voxelization.

    $\begingroup$ Can you not subdivide your world into a 3d grid and if any grid has >= 1 point inside it, it can be made into a voxel? $\endgroup$ – PaulHK May 2 '17 at 9:40
  • $\begingroup$ You could use a fullscreen triangle and raymarch it. There's lots of tutorials about that. And iirc it's the preferred method. $\endgroup$ – z0rberg's May 16 '17 at 7:06
  • $\begingroup$ Why do you need voxels to begin with? Can't you just render the points themselves (possibly with some adaptive point size)? $\endgroup$ – Christian Rau Oct 1 '17 at 20:00
