A journey and a method for drawing spheres

I think it would be interesting to bundle this as a lesson for high school students. Not necessarily because of the trigonometry, but because it seems very engaging.<p>It could be a good lead-in to a lesson on straight-edge &amp; compass constructions, which is pretty fun.

This is such a wonderful article, I wish there were more like this out. Thank you for a delightful contribution to educational resources.

It&#x27;s very interesting to see a post on drawing from a programmer perspective.

Isn&#x27;t this essentially just projecting a 3d sphere onto a 2d surface, but evaluating the transformation components without putting them in matrix form?
