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.
