class IndexedFaceSet from Vrml inherits TShared from MMgt
---Purpose: defines a IndexedFaceSet node of VRML specifying geometry shapes.
-- This node represents a 3D shape formed by constructing faces (polygons) from
-- vertices located at the current coordinates. IndexedFaceSet uses the indices
-- in its coordIndex to define polygonal faces. An index of -1 separates faces
-- (so a -1 at the end of the list is optional).
-- The vertices of the faces are transformed by the current transformation matrix.
-- Treatment of the current material and normal binding is as follows: The PER_PART
-- and PER_FACE bindings specify a material or normal for each face. PER_VERTEX
-- specifies a material or normal for each vertex. The corresponding _INDEXED bindings
-- are the same, but use the materialIndex or normalIndexindices. The DEFAULT material
-- binding is equal to OVERALL. The DEFAULT normal binding is equal to PER_VERTEX_INDEXED;
-- if insufficient normals exist in the state, vertex normals will be generated
-- automatically. When materialIndex or normalIndex are specified on a per vertex basis,
-- an index of -1 is used in the same way as coordIndex.
