Hi Dirk, I see some differences on our systems, but I don't know if they may cause the artifacts you encounter or even if they may appear in mine :) My single constraint correction step is the same as yours, but I do not use the same w_sor for all constraints. My edge constraints use no SOR, Shear (...

Hi Dirk, I implemented a system similar to Meggs' but on regular meshes instead of triangle meshes and didn't notice the artifacts you mention... are you enforcing all the constraints to be met in a single step? or in Maggs' words, what are your "bias" values for length and bending constra...

Havok 4.0 video

Interesting video at:

Shows massive "rigid particles" simulations at reasonable fps running on the GPU.

Hi all, There was a nice presentation on "verlet clothes on characters" at GDC 2005 from the guy who added cloth physics to the Source engine for Vampire: The Masquerade: https://www.cmpevents.com/sessions/GD/ParachutePants.pps It's a very good presentation and the ideas there actually *wo...
