softbody for clothing simulation

Post by Yann »

Hello,
I tried to use softBody simulation of Bullet to make clothing simulation but I'm quite unhappy with the results: it works (somehow) for simple cloth simulation like a cape, but it does not gives any good result for something more complex like a full dress with collisions on legs with a walking character.

I also tried Nvidia PhysX and Apex, and they use a something they call "Hybrid Cloth" that is kind of a mix of skinning techniques combined with soft body simulation. It gives quite good results, and I was wondering if there was anyway to build one with Bullet btSoftBody ?

In short, what would be needed would be:
- a way to give each vertex of the soft body a maximum radius where it could be allowed to move
- a way to give each vertex a "starting position" at each frame

Does anybody ever tried this in Bullet ? Does anybody see if/how it could be possible ?

Here a few details on the hybrid system: http://physxinfo.com/wiki/APEX_Clothing
Quite more details in the Apex documentation
