public class PointAttributes
The PointAttributes object defines all attributes that apply to point primitives. The point attributes that can be defined are:
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.
