How can I enable Continuous Collision Detection (CCD) in Bullet Physics?

The Bullet Physics SDK contains a CCD physics demo in Demos/CcdPhysicsDemo/CcdPhysicsDemo.cpp. Have you tried taking a look at the code to learn what they do? Engine demos exist for a reason. ;) – Jonathan Hobbs May 5 '11 at 7:11

You need to enable CCD per object as described in Bullet wiki or Panda3D Manual: Bullet Continuous Collision Detection. Basically you need to set body->setCcdMotionThreshold(...); and body->setCcdSweptSphereRadius(0.2f);

So if I'm shooting bullets, which are very small, this value need to be quite small, isn't this a disadvantage ? – jokoon Feb 10 at 21:41
