In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
Rotation about an arbitrary axis Rotation about an arbitrary axis is a composition of several rotations and translation operations. What you need to do is the following: a)
