Overview

   This factory is used to generate facet or averaged vertex normals for input geometries. 

Clauses

    MODE
        FACET
            The vertex normal is set identical to the surface normal of the face.
            This is the default setting.

        AVERAGED
            The vertex normal is the average of all the surface normals of the faces that include the vertex.

Output Tags

   OUTPUT

      Features output with facet or averaged vertex normals.
