[vtkusers] Point cloud downsampling/voxelization

[peterm]

Hi

What about creating a 3D binary image over a specified domain, and setting
the cell values to 1 in case a certain condition is met based on the point
cloud data (e.g. a threshold on the point count inside the voxels), and
extracting the surface mesh using some specific tools (e.g. like marching
cubes)?
