Detailed Description

Indexed triangle strip set shape node.

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, Open 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.

To render triangles that are not in strips, see the SoIndexedTriangleSet node.
