Real-Time Physics Simulation Forum

Hi everyone, I have some trouble in my project.

I want to use bullet collision detection & feedback in my elastic deformable body simulation.

But I have no idea.

Anyone can give me some direction?
Is there some demo source code?

I have same question.
I find many people use btDvbt to create a aabb tree.
I tried it but for me it's very slow to update aabb tree. Maybe because my code.
If you find better solution please tell me.
Thank you.
