Donut math: how donut.c works

Reminds me of this classic IOCCC entry implementing a flight simulator, where portions of the source code are formatted to resemble a plane:<p><a href="https:&#x2F;&#x2F;www.ioccc.org&#x2F;1998&#x2F;banks.orig.c" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.ioccc.org&#x2F;1998&#x2F;banks.orig.c</a><p><a href="https:&#x2F;&#x2F;www.ioccc.org&#x2F;years.html#1998_banks" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.ioccc.org&#x2F;years.html#1998_banks</a>

Interesting.<p>Tangentially reminds me of my own animated GIF app that I made a while ago.<p><a href="https:&#x2F;&#x2F;www.gifcii.fun" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.gifcii.fun</a>

That’s the kind of thing that had me learn coding many years ago ( watching demoscene productions).

What platform does this compile on? Didn&#x27;t work for me on a recent model M1 MacBook Pro.

reminds me of stuff i based in basic when i was a kid<p>made me laugh to see &quot;no raytracing&quot;, then immediate use of the perspective projection which is intersecting points and a plane along a ray lol...
