public class RotationShape3D
extends javax.media.j3d.Shape3D

This class generates an rotation symmetric object out of a coordinate array which describes its hull. It bases on source code by Dr. Andrew Davison (http://fivedots.coe.psu.ac.th/~ad/jg)

Field Detail

ENABLE_APPEARANCE_MODIFY

public static final int ENABLE_APPEARANCE_MODIFY

This flag specifies that the objects appearance has to be read- and writeable also after compilation. It causes this class to set the required capability bits for the underlying Shape3D

ENABLE_PICK_REPORTING

public static final int ENABLE_PICK_REPORTING

This flag specifies that the objects has to pickable also after compilation. It causes this class to set the required capability bits for the underlying geometry data

Constructor Detail

RotationShape3D

public RotationShape3D(double[] xsIn,
                       double[] ysIn)

Default constructor for a rotation symmetric object. It generates a white, non-elliptic RotationShape3D.

Parameters:

xsIn - x-coordinate array which describes the hull of the object

ysIn - y-coordinate array which describes the hull of the object

RotationShape3D

public RotationShape3D(int flags,
                       double[] xsIn,
                       double[] ysIn,
                       double zRadiusFactor,
                       int divisions,
                       javax.media.j3d.Appearance App)

Constructor for a rotation symmetric object.

Parameters:

flags - specifies which Primitive-flags have to be used for the object creation

xsIn - x-coordinate array which describes the hull of the object

ysIn - y-coordinate array which describes the hull of the object

zRadiusFactor - specifies if a elliptic object has to be created; if this value is euqal 1.0 the object won't be elliptic, values smaller 1.0 cause the model to be shrinked in z-direction, values greater 1.0 let it expand in z-direction

divisions - specifies the number of subdivision which have to be used to generate the object, this value has to be at least 3

App - the Appearance for this object

RotationShape3D

public RotationShape3D(int flags,
                       float[] xsIn,
                       float[] ysIn,
                       double zRadiusFactor,
                       int divisions,
                       javax.media.j3d.Appearance App)

Constructor for a rotation symmetric object.

Parameters:

flags - specifies which Primitive-flags have to be used for the object creation

xsIn - x-coordinate array which describes the hull of the object

ysIn - y-coordinate array which describes the hull of the object

zRadiusFactor - specifies if a elliptic object has to be created; if this value is euqal 1.0 the object won't be elliptic, values smaller 1.0 cause the model to be shrinked in z-direction, values greater 1.0 let it expand in z-direction

divisions - specifies the number of subdivision which have to be used to generate the object, this value has to be at least 3

App - the Appearance for this object

                       int divisions)

Constructor for a white rotation symmetric object.

Parameters:

xsIn - x-coordinate array which describes the hull of the object

ysIn - y-coordinate array which describes the hull of the object

zRadiusFactor - specifies if a elliptic object has to be created; if this value is euqal 1.0 the object won't be elliptic, values smaller 1.0 cause the model to be shrinked in z-direction, values greater 1.0 let it expand in z-direction

divisions - specifies the number of subdivision which have to be used to generate the object, this value has to be at least 3
