public class PointAttributes

extends NodeComponent

The PointAttributes object defines all rendering state that can be set as a component object of a Shape3D node.

Field Summary

static int	ALLOW_ANTIALIASING_READ Specifies that this PointAttributes object allows reading its point antialiasing flag.
static int	ALLOW_ANTIALIASING_WRITE Specifies that this PointAttributes object allows writing its point antialiasing flag.
static int	ALLOW_SIZE_READ Specifies that this PointAttributes object allows reading its point size information.
static int	ALLOW_SIZE_WRITE Specifies that this PointAttributes object allows writing its point size information.

Constructor Summary

PointAttributes()
Constructs a PointAttributes object with default parameters.

PointAttributes(float pointSize, boolean pointAntialiasing)
Constructs a PointAttributes object with specified values.

Method Summary

NodeComponent	cloneNodeComponent() Creates a new PointAttributes object.
void	duplicateNodeComponent(NodeComponent originalNodeComponent) Copies the information found in originalNodeComponent to the current node.
boolean	getPointAntialiasingEnable() Retrieves the state of the point antialiasing flag.
float	getPointSize() Gets the point size for this appearance component object.
void	setPointAntialiasingEnable(boolean state) Enables or disables point antialiasing for this appearance component object.
void	setPointSize(float pointSize) Sets the point size for this appearance component object.

Constructor Detail

PointAttributes

public PointAttributes()

Constructs a PointAttributes object with default parameters. The default values are as follows:

point size : 1
point antialiasing : false

PointAttributes

public PointAttributes(float pointSize,
                       boolean pointAntialiasing)

Constructs a PointAttributes object with specified values.

Parameters:

pointSize - the size of points.

pointAntialiasing - flag to set point antialising ON or OFF

Method Detail

setPointSize

public final void setPointSize(float pointSize)

Sets the point size for this appearance component object.

Parameters:

pointSize - the size, in pixels, of point primitives

Throws:

CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

getPointSize

public final float getPointSize()

Gets the point size for this appearance component object.

Returns:

the size, in pixels, of point primitives

Throws:

CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

setPointAntialiasingEnable

public final void setPointAntialiasingEnable(boolean state)

Enables or disables point antialiasing for this appearance component object.

Parameters:

state - true or false to enable or disable point antialiasing

Throws:

CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

getPointAntialiasingEnable

public final boolean getPointAntialiasingEnable()

Retrieves the state of the point antialiasing flag.

Returns:

true if point antialiasing is enabled, false if point antialiasing is disabled

Throws:

CapabilityNotSetException - if appropriate capability is not set and this object is part of live or compiled scene graph

cloneNodeComponent

public NodeComponent cloneNodeComponent()

Creates a new PointAttributes object. Called from a Leaf node's duplicateNode method.

Overrides:

cloneNodeComponent in class NodeComponent

Returns:

a duplicate of the PointAttributes object.

Node.cloneTree(), Node.cloneNode(boolean), NodeComponent.duplicateNodeComponent(javax.media.j3d.NodeComponent), NodeComponent.setDuplicateOnCloneTree(boolean)

duplicateNodeComponent

public void duplicateNodeComponent(NodeComponent originalNodeComponent)

Copies the information found in originalNodeComponent to the current node. This routine is called as part of the cloneTree operation.

Overrides:

duplicateNodeComponent in class NodeComponent

Parameters:

originalNodeComponent - the node to duplicate.
