Keenan Crane back once again with the ~~renegade master~~ shithot diagrams! For those not familiar, check his publications with ridiculously beautiful diagrams, going way back (I remember when he was maybe best known for a Quaternion Julia tracer, often used to benchmark GPU FLOPs): https://www.cs.cmu.edu/~kmcrane/ https://www.cs.cmu.edu/~kmcrane/ Also fun for topological nightmare enjoyers is his "Yeah Right" model on https://www.cs.cmu.edu/~kmcrane/Projects/ModelRepository/ https://www.cs.cmu.edu/~kmcrane/Projects/ModelRepository/ (img link: https://www.cs.cmu.edu/~kmcrane/Projects/ModelRepository/yeahright.png https://www.cs.cmu.edu/~kmcrane/Projects/ModelRepository/yea...)

  Eh, the field is called computer graphics, so having nice graphs is to be expected isn't it?

    'graphics' yes, but 'nice' would be nice because they often aren't.

      That was just a lame pun, but looks like HN doesn't like my sense of humor.

      I'm a physicist, and my go-to conference joke is "It's remarkable that so many people who know so much about vectors know so little about vector graphics"

    Clearly you haven’t read a lot of research papers in computer graphics, geometry processing, and shape analysis.

      It's funny because I initially wrote my comment with a final “/s”, before removing it right after I submitted it “because it's already obvious it's a joke”. Incorrect assessment it seems…

  > back once again with the ~~renegade master~~ Wow, that just started a song playing in my head that I'd completely forgotten about for like 20 years. The version I know best is the Fatboy Slim remix: https://www.youtube.com/watch?v=xVb6ZuXrhXk https://www.youtube.com/watch?v=xVb6ZuXrhXk I played the hell out of that track.

    yeah, love it too

  Created an account just to say that my student Mark Gillespie made most of the figures in this paper, and is himself quite the renegade master: https://markjgillespie.com/ https://markjgillespie.com/

Cool as hell. Keenan Crane has excellent YouTube series on discrete differential geometry and computer graphics. Hopefully this will lead to nicer physics graphics since harmonic functions are everywhere.
