Module Description

CleaverExtension is a Slicer CLI Module that takes a set of NRRD Volumes and creates a set of tetrahedral meshes to import into the Slicer MRML.

Based on the "Lattice Cleaving" algorithm (see References), this method is theoretically guaranteed to produce valid meshes with bounded dihedral angles, while still conforming to multimaterial material surfaces. Empirically these bounds have been shown to be significant.
