DESCRIPTION
     This shape node constructs triangle strips out of vertices located at the
     coordinates specified in the vertexProperty field (from SoVertexShape),
     or the current inherited coordinates. For optimal performance, the
     vertexProperty field is recommended.

     SoIndexedTriangleStripSet uses the indices in the coordIndex field (from
     SoIndexedShape) to specify the vertices of the triangle strips. An index
     of SO_END_STRIP_INDEX (-1) indicates that the current strip has ended and
     the next one begins.

     The vertices of the faces are transformed by the current transformation
     matrix. The faces are drawn with the current light model and drawing
     style.

     Treatment of the current material and normal binding is as follows:
     PER_PART specifies a material or normal per strip. PER_FACE binding
     specifies a material or normal for each triangle. PER_VERTEX specifies a
     material or normal for each vertex. The corresponding _INDEXED bindings
     are the same, but use the materialIndex or normalIndex indices (see
     SoIndexedShape).  The default material binding is OVERALL. The default
     normal binding is PER_VERTEX_INDEXED

     If any normals (or materials) are specified, Inventor assumes you provide
     the correct number of them, as indicated by the binding. You will see
     unexpected results if you specify fewer normals (or materials) than the
     shape requires. If no normals are specified, they will be generated
     automatically.

METHODS
                         SoIndexedTriangleStripSet()
          Creates an indexed triangle strip set node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


ACTION BEHAVIOR
     SoGLRenderAction
          Draws a strip set based on the current coordinates, normals,
          materials, drawing style, and so on.

     SoRayPickAction
          Picks on the strip set based on the current coordinates and
          transformation. Details about the intersection are returned in an
          SoFaceDetail.

     SoGetBoundingBoxAction
          Computes the bounding box that encloses all vertices of the strip
          set with the current transformation applied to them. Sets the center
          to the average of the coordinates of all vertices.

     SoCallbackAction
          If any triangle callbacks are registered with the action, they will
          be invoked for each successive triangle forming the strips of the
          set.
