#JOGL A simple Paddle Wheel

In this program, which the author David J Eck describes as a simple 3D program(chapter: Geometry) in his graphics book, a paddle wheel is being drawn. We can define a polygon in the x-y plane above the x axis and rotate it wrt the x axis each time with varying angles. Then to get a 3D look we tilt the paddle wheel by rotating about y axis.
