I have had the same idea about martial arts. Not sure it is possible. In dancing you have at least some symmetric patterns and rhythm, in martial arts you have even more stances, rotation around more axes and arrhythmic moves. good dancing like good fighting isn‘t mechanical either, it is good because it relies on little imperfections. Just like MIDI files cannot replace a concert pianist. In the end I think motion capture of extremities along with some easing of paths and compression of point-clouds (think bezier curves) might be more worthwhile than a notation.

> in martial arts you have even more stances, rotation around more axes and arrhythmic moves. I wonder how true this is. Specifically I think you could simplify the moves into steps with "who hits who" states. You could normalise out the rhythm, following the "everything's in 4/4 if you don't count like a nerd" idea. So you'd end up with just the key frames of either contacts/impact or change of the movement direction. Would martial arts really have even more variety here?

    I'm experienced with both sides here. I think they're fairly comparable in moves/complexity if you include the non-partnered dances in general.

Somebody sort of did something like this, not exactly the same, but I think'll get a kick out of it. I don't do martial arts but as part of the research I looked into how people represent martial arts in written or abstracted form. During this time, late one night, I found this website: http://eel.is/GrappleMap/index.html http://eel.is/GrappleMap/index.html It turns out one guy made a website that let you simulate a ton of BJJ moves and sequences, designing an abstract BJJ representation as well as making a 3d animator/viewer for those animations http://eel.is/GrappleMap/composer/index.html?484,517,518,1259,636,1189 http://eel.is/GrappleMap/composer/index.html?484,517,518,125... It's all up on github https://github.com/Eelis/GrappleMap/ https://github.com/Eelis/GrappleMap/ and some sample videos can be seen here https://www.youtube.com/watch?v=rC7zTBMPj1Y https://www.youtube.com/watch?v=rC7zTBMPj1Y https://www.youtube.com/watch?v=MAeBgGZ1GdM https://www.youtube.com/watch?v=MAeBgGZ1GdM http://eel.is/GrappleMap/index.html http://eel.is/GrappleMap/index.html I spent hours messing around with this, he got it working in VR too. More or less one guy just writing a ton of C++ on his own to make something incredible. https://github.com/Eelis/GrappleMap/graphs/contributors https://github.com/Eelis/GrappleMap/graphs/contributors
