public class Cylinder3D
extends GRShadedShape

This actor contains the geometry and appearance specifications for a GR cylinder. The output port is used to connect this actor to the Java3D scene graph. This actor will only have meaning in the GR domain. Note that most of the parameters are described in the base class documentation.

Field Detail

circleDivisions

public Parameter circleDivisions

The number of divisions in the circles forming the ends of the cylinder. This is an integer with default value "max(6, roundToInt(radius * 100))". This parameter determines the resolution of the cylinder, which is approximated as a surface composed of rectangular facets. Increasing this value makes the surface smoother, but also increases the cost of rendering.

height

public Parameter height

The height of the cylinder. This is a double with default 0.7.

sideDivisions

public Parameter sideDivisions

The number of divisions on the side of the cone. This is an integer with default value "1". This parameter probably only needs to change when the wireFrame option is set to true.

radius

public Parameter radius

The radius of the cylinder. This is a double with default 0.5.

_scaleTransform

private javax.media.j3d.Transform3D _scaleTransform

If changes to the radius are allowed, this is the transform that applies them.

_containedNode

private javax.media.j3d.Node _containedNode

The contained cylinder.

Constructor Detail

Cylinder3D

public Cylinder3D(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.

NameDuplicationException - If the container already has an actor with this name.

Method Detail

attributeChanged

public void attributeChanged(Attribute attribute)
                      throws IllegalActionException

If the dimensions change, then update the box.

Overrides:

attributeChanged in class GRShadedShape

Parameters:

attribute - The attribute that changed.

Throws:

IllegalActionException - If the change is not acceptable to this container (not thrown in this base class).

_createModel

protected void _createModel()
                     throws IllegalActionException

Create the shape and appearance of the encapsulated cylinder.

Overrides:

_createModel in class GRShadedShape

Throws:

IllegalActionException - If the value of some parameter can't be obtained.

_getNodeObject

protected javax.media.j3d.Node _getNodeObject()

Return the encapsulated Java3D node of this 3D actor. The encapsulated node for this actor is a Java3D Cylinder.

Specified by:

_getNodeObject in class GRActor3D

Returns:

The Java3D Cylinder.
