rotate

Syntax:

	(rotate
		(axis: coord (axis))
		(angle: number (angle))
		(object: gprim))

axis:

The axis of rotation (will be normalize). For convenience, the global variables yaw, roll, and pitch are bound to (: 0 1 0), (: 0 0 1), and (: 1 0 0).

angle:

Angle specifying how far to rotate around axis. The angle is in degrees.

object:

An arbitrary tree which contains of graphics primitive objects.

Example:

(rotate (axis: pitch) (angle: 45) (object: (Cone (radius:3)))

This code rotates a radius 3 cone 45 degrees counter-clockwise about the x axis.
