Detailed Description

Each triangle consists of 3 vertices, each of which is denoted by an integer index (from the coordIndex field) into the current coordinates. This is a specialized version of SoIndexedFaceSet, which offers slightly faster updates/rendering, since it only renders triangles. Unlike SoIndexedFaceSet, no -1 separators in the coordIndex field are needed nor supported. Depending on the current material and normal binding values, the materials and normals for the faces or vertices may be accessed in order or indexed. If they are indexed, the materialIndex and normalIndex fields are used.

(MeVis ONLY, VSG3D also has this node)
