Detailed Description

Inverse-distance-weighted interpolation stencil.

hole finding:

mark boundary faces on helper (voxel) mesh
mark any cell overlaying these voxels
use flood filling to find any unreachable cell Alternative is to use an octree of the boundary faces and determine directly for all cells whether we are outside. Might be slow though.
