Repulsive Shells [video]

The ending was unexpected but great haha. I'm curious if the algo is fast enough for real time or if it's only for renders.

Yeah, likewise. It definitely looks like it's formulated for optimizing paths rather than, say, simulating real-time physics, so I'm guessing not yet. From a quick scan of the paper, I didn't see anything on the complexity (O(N logN) or O(N^2) or whatever), but there were some timings:

> Figures 11 [clasped hands] and 15 [underwear model] each took first 10 minutes to find a coarse trajectory, then 5 and 2-3 minutes, respectively, to refine [to 60 fps].

Those numbers don't mean much beyond "minutes are better than days", because this contribution is a quality improvement via a new algorithm. Optimizing performance and maximizing choice of hardware power is another effort.
