public class PointAttributes extends NodeComponent
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 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.

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)

pointSize
- the size of points, in pixelspointAntialiasing
- flag to set point antialising ON or OFF
-

setPointSize
public 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 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 void setPointAntialiasingEnable(boolean state)
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- Throws:
CapabilityNotSetException
- if appropriate capability is not set and this object is part of live or compiled scene graph- See Also:

getPointAntialiasingEnable
public 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
