public class Rotate3D
extends GRTransform

Conceptually, this actor takes 3D geometry in its input and produces a rotated version in its output. In reality, this actor encapsulates a Java3D TransformGroup which is converted into a node in the resulting Java3D scene graph. This actor will only have meaning in the GR domain. The parameters axisDirectionX,axisDirectionY, and axisDirectionZ determine the direction of the axis of rotation. The parameters baseX, baseY, and baseZ determine the pivot point for axis of the rotation. The parameter initialAngle determines the initial angle of rotation.
