Class SbProjectionCoordinates

java.lang.Object

com.openinventor.inventor.Inventor

com.openinventor.inventor.projection.SbProjectionCoordinates

public class SbProjectionCoordinates
extends Inventor

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.
