public class CircularSweep3D
- extends GRShadedShape
This actor contains the geometry and appearance specifications for a
circularly swept object. The output port is used to connect this
actor to the Java3D scene graph. This actor will only have meaning
in the GR domain.
The parameter polyline determines the silhouette of the
object. One will need to enter an array of coordinates in the X-Y
plane to specify the contour for this silhouette. The parameter
angleSpan determines the angle in which the silhouette is
swept. The parameter slices determines the number of
polygonal slices used in the sweep.

polyline
public Parameter polyline
- The line segment array that is to be swept.
This is an array of doubles that defaults to
a square with sides of 0.25 shifted right from
the origin so its left edge is at x = 0.25.
This results in an annular sweep.
angleSpan
public Parameter angleSpan
- The span of sweep angle. This is a double that
defaults to "2.0 * PI".
slices
public Parameter slices
- The number of slices. This is an integer
that defaults to 32. Higher numbers result
in a smoother sweep.
_containedNode
private javax.media.j3d.Shape3D _containedNode
- The contained node.
CircularSweep3D
public CircularSweep3D(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.
_createModel
protected void _createModel()
throws IllegalActionException
- Create the shape and appearance of the encapsulated swept surface.
- 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 circular sweep.
- Specified by:
_getNodeObject
in class GRActor3D
- Returns:
- the Java3D circular sweep
_getPolyline
private float[] _getPolyline()
throws IllegalActionException
- Return the polyline as an array of floats.
- Returns:
- The polyline.
- Throws:
IllegalActionException
- If polyline parameter
cannot be evaluated.
_getVertexCount
private int _getVertexCount()
throws IllegalActionException
- Return the number of vertices of the polyline.
- Returns:
- The vertex count.
- Throws:
IllegalActionException
- If the polyline parameter
cannot be evaluated.
