Does anyone know how to create a Collider deformer? What I mean is something like this:

Maybe you can tweak the MPM solver to get what you want.

It could matter how accurate you need to be. MPM is an awesome approach that is very good at large deformations for materials with physical properties. There is a lot of literature and research into its use in Houdini for over 10+ years. Therefore one hopes that Houdini would put something special together since MPM is a generalization of FLIP/APIC. There is real experience with the MPM technology at Houdini.

Currently, it does not perform as well as other options such as Warp: https://nvidia.github.io/warp/, [nvidia.github.io] it may be because of the over reliance on generic OpenCL and not device specific solvers? Or really beautiful visual renders that "make-up" for the bottleneck in aesthetics? I think that for physics and materials properties that we do know for a fact, there will should be neural fields that we apply to the points.

If it is not for accuracy:
There are a few other routes if it is too slow or not "art-directable" enough.

There is the

- Sensor Deform: https://www.sidefx.com/docs/houdini/nodes/vop/sensor_panorama_create.html [www.sidefx.com] (look at the example file at bottom)
- Point Deform: https://www.youtube.com/watch?v=iejHx2AczJk [www.youtube.com]
- SOP Solver approaches: https://www.youtube.com/watch?v=rGNtGkuZdsA&t=408s [www.youtube.com]

Here are Neural MPM Simulations with Warp:

I'm quite sure the OP was asking something real time (at a cost of accuracy) similar to the new wrinkle deform in H20.5. So MPM isn't quite applicable here.

Yes, I am looking for a static SOP solver, it you take a look at the videos I linked its just a deformer with some ray casting. A lot like wrinkle deformer yes.

Iterate over the ray node set to minimum distance combined with the wrinkle deformer.

That is amazing. Thank you.
Exactly what I was looking for. Sorry for the stupid question but - do you have an idea about how to eliminate self intersection like this:
