SoTriangleStripSet(3) on Linux
The text 74be646ad373, as Debian 4.0 (Etch) shipped it.
The SoTriangleStripSet class is used to render and control non-indexed triangle strips. Triangle strips are specified using the numVertices field. Coordinates, normals, materials and texture coordinates are fetched in order from the current state or from the vertexProperty node if set. For example, if numVertices is set to [3, 4, 5, 3], this node would specify a triangle from coordinates 0, 1 and 2, a triangle strip from coordinates 3, 4, 5 and 6, a triangle strip from coordinates 7, 8, 9, 10 and 11 and finally a triangle from coordinates 12, 13, 14.
