This is kinda fun – makes me wonder how soon we can expect some form of this technology in Houdini? (I'm sure the SideFX guys are already working on trying to figure it out)

Link to the actual paper's video:

Sidefx often implements new research, but these things take time. It also depends on whether or not a new technique is viable in applications that are in Houdini's scope of use (VFX). Simulations that take 100's of hours may be okay for research, but to be usable in vfx the simulation time has to be much more reasonable.

Point-based simulations are also difficult to apply to existing meshes that require high quality uv preservation.

That said, some form of MPM would be nice to see in Houdini, even if it isn't new research.

I guess Grains and Vellum could possibly yield similar results. A multi-density/multi-glue constraint type of system, so effectively Vellum on steroids.

I wonder if this is where Vellum is headed?

MPM is very different from Vellum, seems closer to FLIP and FEM

Would be great to have it in Houdini though as it's pretty impressive and useful for certain types of effects

I heard new Bifrost in Maya has pretty robust MPM solver, so would be good to keep an eye on that too
