SoIndexedPointSet(3) on Linux
The text ef107825e9f0, as Debian 6.0 (Squeeze) shipped it.
The SoIndexedPointSet class is used to display a set of 3D points. This node either uses the coordinates currently on the state (typically set up by a leading SoCoordinate3 node in the scenegraph) or from a SoVertexProperty node attached to this node to render a set of 3D points.
