The point attributes that can be defined are:<p> <ul> <li>Size - the size of the point, in pixels. The default is a point size of one pixel.</li><p> <li>Antialiasing - for points greater than one-pixel in size, antialiasing smooths the outline of the point when it is rendered.</li> <p></ul> If antialiasing is disabled (the default), fractional point sizes are rounded to integer sizes, and a screen-aligned square region of pixels is drawn.<p> <p> 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.
