       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.


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


          Creates a triangle strip set node with default settings.

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


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

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

          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.

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