Detailed Description

Cache projected coordinates.

This class stores the projected coordinates associated with a given geometry node and a given SoProjection node during a scene graph traversal. Each instance of SbProjectionCoordinates maintains a cache, based on the node IDs of the associated node and projection node. Calling resetCache() will force the projected coordinates to be recomputed during the next traversal.
