DESCRIPTION

61       This node defines a set of 3D coordinates to be used by subsequent ver‐
62       tex-based shape nodes (those derived from SoVertexShape) or shape nodes
63       that  use  them  as control points (such as NURBS curves and surfaces).
64       Coordinates are specifed as rational 4-vectors;  the  corresponding  3D
65       point is computed by dividing the first three components by the fourth.
66       This node does not produce a visible result during rendering; it simply
67       replaces  the current coordinates in the rendering state for subsequent
68       nodes to use.
69
70       This node exists primarily for use with NURBS curves and surfaces. How‐
71       ever, it can be used to define coordinates for any vertex-based shape.
