Playing with 3DS Max 5 in high school was such a “portal to the future” feeling. I loved the physics and cloth sims. But come to think of it… has anyone ever seen a cloth simulation where the cloth can be more realistically rolled up or knotted, twisted, or otherwise doing things requiring a sense of volume and mass?

[SIGGRAPH 2017] Anisotropic Elastoplasticity for Cloth, Knit and Hair Frictional Contact: https://vimeo.com/219585631 If that doesn't do it for you, there's a lot more options in the SIGGRAPH paper list at https://kesen.realtimerendering.com/

As an ex-3D developer, these videos are wild. Thank you.

There are a few amazing blendr plug-ins I've seen recently.

They have a workflow that is basically draw 2d patterns, stitch those together, then drape it over and let the simulation determine how it sits.

It seems like it's super powerful for clothing designers, and soft goods designers too.

YouTube has more info

Straight from the oven (paper from SIGGRAPH 2023): "Multi-Layer Thick Shells" (https://youtube.com/watch?v=z1Wc5DvC2Wk) Extends the FEM model to accommodate for thick shell-like structures, like yoga mats, leather, and wrinkles on matrices.

Also you might want to check out the IPC papers (particularily C-IPC, since you said you're interested in cloth: https://www.youtube.com/watch?v=jvBSDXxsgRA). A new class of simulation methods has arisen over the years which allow you to simulate detailed collisions in an incredibly robust way (though computation time is still an issue).

nice....

this looks to me a cotton "cloth"...

how about adding properties that it can act as a blanket or a silk cloth or a jute cloth or a tough starchy cloth or stuff like ironed shirt or unironed shirt?

Fun Trivia: Feynman's son worked on cloth simulation for his MIT MSc Thesis back in '87! https://dspace.mit.edu/handle/1721.1/14924

I believe Einstein's son worked on "Sediment Transport by Rivers". [0]

It must be hard for one to have a high-achieving--or worse, world famous--parent or sibling.

The channel @TwoMinutePapers on YouTube sometimes reports on progress in this area.

I remember when this was mind blowing, although not perfect, in Splinter Cell, on the Xbox, some 20 years ago. Now it’s almost flawless on my phone.

Nocturne (1999) was the first real use of cloth physics I saw in a game.

I remember Thief (1998) as having curtains that moved while hiding behind them.

Very impressive. I use the cloth simulation in Daz Studio, and I wish it was as performant as this. It can take 20 mins only to have the cloth ‘explode’ when it intersects something unexpectedly. That said the obstacles are more complex than spheres
