public class Translate3D
extends GRTransform

Conceptually, this actor takes 3D geometry in its input and produces a translated 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.

Field Detail

xTranslate

public TypedIOPort xTranslate

The amount of translation in the x-axis during firing. If this transform is in accumulate mode, the translation value is accumulated for each firing.

yTranslate

public TypedIOPort yTranslate

The amount of translation in the y-axis during firing. If this transform is in accumulate mode, the translation value is accumulated for each firing.

zTranslate

public TypedIOPort zTranslate

The amount of translation in the z-axis during firing. If this transform is in accumulate mode, the translation value is accumulated for each firing.

initialXTranslation

public Parameter initialXTranslation

The initial translation in the x-axis This parameter should contain a DoubleToken. The default value of this parameter is 0.0.

initialYTranslation

public Parameter initialYTranslation

The initial translation in the y-axis This parameter should contain a DoubleToken. The default value of this parameter is 0.0.

initialZTranslation

public Parameter initialZTranslation

The initial translation in the z-axis This parameter should contain a DoubleToken. The default value of this parameter is 0.0.

_transformNode

protected javax.media.j3d.TransformGroup _transformNode

The encapsulated Java 3D node of this actor.

Constructor Detail

Translate3D

public Translate3D(CompositeEntity container,
                   java.lang.String name)
            throws IllegalActionException,
                   NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

IllegalActionException - If the actor cannot be contained by the proposed container.
