## Detailed Description

Convert polygonal meshes that consist of quads and/or triangles into signed or unsigned distance field volumes.

Note
  The signed distance field conversion requires a closed surface but not necessarily a manifold surface. Supports surfaces with self intersections and degenerate faces and is independent of mesh surface normals / polygon orientation.
