59// Class: SoTriangleStripSet
60//
61// Triangle strip set node. Each strip in the set consists of n
62// vertices located at consecutive entries in the current
63// coordinates. The startIndex field gives the starting coordinate
64// index for the first strip. If materials or normals are bound to
65// vertices, they will begin at that index, as well; otherwise, they
66// will start at index 0. The number of vertices in each strip is
67// determined by successive entries in the numVertices field.
