Standard Gprim Parameters
Most gprims support parameter lists which allow additional
information to be specified on a per vertex (or corner, or polygon) basis.
In addition, users can define additional parameters which will be
passed to the renderer if supported. Parameters in the table below
are "varying" unless otherwise noted.
