Looking for a solver that acts like bending metal?

[ouch67]

is there one?

What I mean is that if you took 2 spheres, where one was a ball bearing and the other was hollow sheet metal and you dropped the ball bearing on the sheet metal one their would be a dent in the sheet metal one. does something like this exist in bullet?

I see gimpact is supposed to have deformable meshes but I couldn't find any function that actually does that. Plus the collision physics of gimpact models are quite bizarre at the moment anyway.

I played with soft meshes trying to get the results I needed but it doesn't seem to be possible with them.

played with gimpact / deformation ...
see small demo
http://game-ws.googlecode.com/files/deform_r774.7z.exe
for source code look at this one, it is the same, but smaller

Yes I saw that but in your source code version nothing actually deforms... So did you add something to bullet to do that or am I missing something?

look for #ifdef TEST_DEFORM in HitTriangleDemo.cpp, ... access the array, modify vertices and call postUpdate()...

ah ok, thanks!
