public abstract class GRTransform

extends VisualSim.simulators.gr.kernel.GRActor3D

An abstract base class for a transform operator of GR shapes. This actor will only have meaning in the GR domain. The parameter accumulate determines whether transformations are accumulated or reset during firing.

Since:

VisualSim1.0

Constructor Detail

GRTransform

public GRTransform(VisualSim.kernel.CompositeEntity container,
                   java.lang.String name)
            throws VisualSim.kernel.util.IllegalActionException,
