fillSimpleHoles MethodStatic

Return a mesh with "some" holes filled in with new facets.

  • Candidate chains are computed by announceBoundaryChainsAsLineString3d.
  • Unclosed chains are rejected.
  • Closed chains are triangulated and returned as a mesh.
  • The options structure enforces restrictions on how complicated the hole filling can be:
    • maxEdgesAroundHole -- holes with more edges are skipped.
    • maxPerimeter -- holes with larger summed edge lengths are skipped.
    • upVector -- holes that do not have positive area along this view are skipped.
    • includeOriginalMesh -- includes the original mesh in the output mesh, so the composite mesh is a clone with holes filled.
