Hello;

We really need a simulation system like "Incremental Potential Contact (IPC)" in Houdini:

Do you agree?

Looks cool. Not sure how much ressources is required to add in houdini dop's

Something new has appeared on SIGGRAPH 2025:
https://ankachan.github.io/Projects/OGC/index.html [ankachan.github.io]
The algorithm is said to be two orders of magnitude faster than IPC/GIPC.

or this one, which seems even more impressive

I feel like I'm in the best restaurant in the world, and have just realised I can't afford anything on the menu : )

It all looks intoxicatingly good, but it sounds like you need a Disney scale farm to use it? It reminds me of talk about global illumination in the 1990's. It was possible, but nobody would implement it because each frame would take about three weeks : )
