Hi, I am trying to simulate denting/plasticity in bullet. Here is a good reference for what I mean by denting: http://vimeo.com/20760525
at the 50-55 second mark.
Here are some basic ideas that I have:
1) Treat the object as a soft body during impact and after a couple frames turn it back into a rigid body.
2) Calculate the dents myself (outside of bullet) using impulses and collision points between the two objects.
Obviously approach #1 gives more control to bullet which might mean greater efficiency. However, I'm wondering if Bullet's soft body feature is customizable enough to create the desired effect.
Before I delve into programming I'm wondering what other people think. What features of bullet will come in handy for doing denting/plasticity?
