Is there SAT algorithm in Bullet Physics Engine

Hi everyone,

I want to change the Collision Detection algorithm to SAT algorithm. I only found GJK algorithm in Bullet. Is there SAT algorithm in Bullet Physics Engine which I can call it directly? Or I have to achieve that by myself?

Thank you in advance!

Is there a lower limit for velocity in Bullet?

Hi all, I set the body in a constant velocity, with setLinearVelocity before stepSimulation. When the velocity is higher than 1 mps, it looks well. But when I set the velocity below 1 mps, such as 0.1 mps, the body stops unbelievably after a few time steps. I'm very confused about it. Is there a low...

How to get the friction force in Bullet?

I'm the beginner of Bullet. In my work, I want to get the friction force between the bodies' interaction. I noticed that m_appliedImpulseLateral1 and m_appliedImpulseLateral2 in btManifoldPoint Class maybe the friction impulse during the contact procress. So I calculated the friction force as follow...
