PointAttributes
public class PointAttributes extends NodeComponent (Code)
The PointAttributes object defines all attributes that apply to point primitives. The point attributes that can be defined are:

  • Size - the size of the point, in pixels. The default is a point size of one pixel.
  • Antialiasing - for points greater than one-pixel in size, antialiasing smooths the outline of the point when it is rendered.
If antialiasing is disabled (the default), fractional point sizes are rounded to integer sizes, and a screen-aligned square region of pixels is drawn.

If antialiasing is enabled, the points are considered transparent for rendering purposes. They are rendered with all the other transparent objects and adhere to the other transparency settings such as the View transparency sorting policy and the View depth buffer freeze transparent enable.

Field Summary
final public static  intALLOW_ANTIALIASING_READ
     Specifies that this PointAttributes object allows reading its point antialiasing flag.
final public static  intALLOW_ANTIALIASING_WRITE
     Specifies that this PointAttributes object allows writing its point antialiasing flag.
final public static  intALLOW_SIZE_READ
     Specifies that this PointAttributes object allows reading its point size information.
final public static  intALLOW_SIZE_WRITE
     Specifies that this PointAttributes object allows writing its point size information.

Constructor Summary
public  PointAttributes()
     Constructs a PointAttributes object with default parameters.
public  PointAttributes(float pointSize, boolean pointAntialiasing)
     Constructs a PointAttributes object with specified values.

Method Summary
public  NodeComponentcloneNodeComponent()
    
 voidcreateRetained()
     Creates a retained mode PointAttributesRetained object that this PointAttributes component object will point to.
 voidduplicateAttributes(NodeComponent originalNodeComponent, boolean forceDuplicate)
     Copies all node information from originalNodeComponent into the current node.
public  booleangetPointAntialiasingEnable()
     Retrieves the state of the point antialiasing flag.
public  floatgetPointSize()
     Gets the point size for this appearance component object.
public  voidsetPointAntialiasingEnable(boolean state)
     Enables or disables point antialiasing for this appearance component object.

If antialiasing is enabled, the points are considered transparent for rendering purposes.

Field Detail
ALLOW_ANTIALIASING_READ
final public static int ALLOW_ANTIALIASING_READ(Code)
Specifies that this PointAttributes object allows reading its point antialiasing flag.



ALLOW_ANTIALIASING_WRITE
final public static int ALLOW_ANTIALIASING_WRITE(Code)
Specifies that this PointAttributes object allows writing its point antialiasing flag.



ALLOW_SIZE_READ
final public static int ALLOW_SIZE_READ(Code)
Specifies that this PointAttributes object allows reading its point size information.



ALLOW_SIZE_WRITE
final public static int ALLOW_SIZE_WRITE(Code)
Specifies that this PointAttributes object allows writing its point size information.




Constructor Detail
PointAttributes
public PointAttributes()(Code)
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)(Code)
Constructs a PointAttributes object with specified values.
Parameters:
  pointSize - the size of points, in pixels
Parameters:
  pointAntialiasing - flag to set point antialising ON or OFF




Method Detail
cloneNodeComponent
public NodeComponent cloneNodeComponent()(Code)



createRetained
void createRetained()(Code)
Creates a retained mode PointAttributesRetained object that this PointAttributes component object will point to.



duplicateAttributes
void duplicateAttributes(NodeComponent originalNodeComponent, boolean forceDuplicate)(Code)
Copies all node information from originalNodeComponent into the current node. This method is called from the duplicateNode method. This routine does the actual duplication of all "local data" (any data defined in this object).
Parameters:
  originalNodeComponent - the original node to duplicate.
Parameters:
  forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.
See Also:   Node.cloneTree
See Also:   NodeComponent.setDuplicateOnCloneTree



getPointAntialiasingEnable
public boolean getPointAntialiasingEnable()(Code)
Retrieves the state of the point antialiasing flag. true if point antialiasing is enabled,false if point antialiasing is disabled
exception:
  CapabilityNotSetException - if appropriate capability isnot set and this object is part of live or compiled scene graph



getPointSize
public float getPointSize()(Code)
Gets the point size for this appearance component object. the size, in pixels, of point primitives
exception:
  CapabilityNotSetException - if appropriate capability isnot set and this object is part of live or compiled scene graph



setPointAntialiasingEnable
public void setPointAntialiasingEnable(boolean state)(Code)
Enables or disables point antialiasing for this appearance component object.

If antialiasing is enabled, the points are considered transparent for rendering purposes. They are rendered with all the other transparent objects and adhere to the other transparency settings such as the View transparency sorting policy and the View depth buffer freeze transparent enable.


Parameters:
  state - true or false to enable or disable point antialiasing
exception:
  CapabilityNotSetException - if appropriate capability isnot set and this object is part of live or compiled scene graph
See Also:   View



setPointSize
public void setPointSize(float pointSize)(Code)
Sets the point size for this appearance component object.
Parameters:
  pointSize - the size, in pixels, of point primitives
exception:
  CapabilityNotSetException - if appropriate capability isnot set and this object is part of live or compiled scene graph
