public class Sphere3D
extends GRShadedShape

This actor contains the geometry and appearance specifications for a sphere. The output port is used to connect this actor to the Java3D scene graph. This actor may be used along with the Scale3D transformer to produce ellipsoid shapes. 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

divisions

public Parameter divisions

The number of divisions in the sphere. This is an integer with default value "max(6, roundToInt(radius * 300))". This parameter determines the resolution of the sphere, which is approximated as a surface composed of triangular facets. Increasing this value makes the surface smoother, but also increases the cost of rendering.

radius

public Parameter radius

The radius of the sphere. This is a double with default 0.1.

_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 sphere.

Constructor Detail

Sphere3D

public Sphere3D(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 specified attribute is the radius, then modify the sphere to the new radius. Note that this will take effect only if the allowRuntimeChanges parameter has value true.

Overrides:

attributeChanged in class GRShadedShape

Parameters:

attribute - The attribute to change.

Throws:

IllegalActionException - If thrown by the parent class.

_createModel

protected void _createModel()
                     throws IllegalActionException

Create the shape and appearance of the sphere.

Overrides:

_createModel in class GRShadedShape

Throws:

IllegalActionException - If the value of some parameters 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 sphere.

Specified by:

_getNodeObject in class GRActor3D

Returns:

the Java3D Sphere
