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

     SoTriangleStripSet is one of the fastest ways of drawing polygonal
     objects in Inventor. It uses the current coordinates, in order, starting
     with the first one. The values in the numVertices field indicate the
     number of vertices to use for each triangle strip in the set. The number
     of values in this field determines the number of strips.

     For example, if numVertices has the values [3,5], coordinates 1, 2, and 3
     would be used for the first triangle strip and coordinates 4, 5, 6, 7,
     and 8 would be used for the second strip. This would result in 1 triangle
     in the first strip and 3 in the second.

     The coordinates of the strips are transformed by the current cumulative
     transformation. The strips are drawn with the current light model and
     drawing style.

     Treatment of the current material and normal binding is as follows: The
     PER_PART binding specifies a material or normal for each strip of the
     set. The PER_FACE binding specifies a material or normal for each
     triangle. The _INDEXED bindings are equivalent to their non-indexed
     counterparts. The default normal binding is PER_VERTEX. The default
     material binding is OVERALL.

     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.

FIELDS
     SoMFInt32           numVertices
          Number of vertices in each triangle strip. The number of strips is
          equal to the number of values in this field.


FUNCTIONS
     SoTriangleStripSet *  SoTriStripSetCreate()
          Creates a triangle strip set node with default settings.

     SoType                SoTriStripSetGetClassTypeId()
          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.
