jv.object.PsObject

jvx.project.PjWorkshop

jvx.geom.PwTransform

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf, PjWorkshopIf

public class PwTransform
extends PjWorkshop

Workshop to perform simple transformations like scaling, translating or rotating on a geometry. All operations are performed for each coordinate axis individually. Rotations and scalings use the center of each geometry as reference point. New tabPanels for mapping of ambient space using functional expressions, or mapping of texture coordinates have been added.
