Mesh

Initializes a new empty mesh.

Protected constructor for internal use.

Gets access to the vertex hidden/visibility collection in this mesh. This is a runtime property and it is not saved in the 3dm file.

Gets the number of disjoint (topologically unconnected) pieces in this mesh.

Gets access to the face normal collection in this mesh.

Will return true if SetCachedTextureCoordinates has been called; otherwise will return false.

HasPrincipalCurvatures

Returns true if every mesh "edge" has two or more faces.

Returns true if the mesh is manifold and every pair of faces that share an "edge" have compatible orientations.

Ngons represent groups of Faces (triangles + quads).

Faces are used to tessellate an Ngon internally.

When a triangle or quad is referenced in the Ngon list, it is no longer visualized and conceived as a single entity, but takes part of the Ngon.

If you need to get access to both Ngons and the faces that are not referenced by Ngons, that is, all polygons that are visible in the mesh, then use the GetNgonAndFacesEnumerable() helper method.
