Hi, I'm not sure my resolution to this will help anyone else but as I've inadvertently managed to fix the problem, I'll detail what I did. To debug the narrow phase collision detection, I replaced the shared Bullet libs I was using (v2.8.3), with what I thought was the same version of BulletCollisio...

Hi, a lot of views for this question but no responses, so I'm not sure if there's a lack of specific detail or the post is too wordy. It might help if I re-phrase and simplify the question: What could cause Bullet to report overlapping pairs with an empty manifold, when a ghost object collides with ...

Hi, I have a Kinematic platform (box) object and a btKinematicCharacterController object, both of which I can move around under user control. If I move the character object so it collides with the stationary platform, the "recoverFromPenetration" function in the btKinematicCharacterControl...

My guess is that the inertia tensors are not being properly computed. If you supply a zero inertia tensor then the object will not rotate (it behaves as if it had infinite rotational mass). Maybe look at the bottom of this forum thread . Bingo! That solved it. Thanks very much. Turned out I was set...

Hi, I've integrated Bullet into numerous small projects and utilised static, kinematic and dynamic objects to good effect. A recent major refactor has resulted in odd behaviour for dynamic objects and I'm hoping for suggestions on where to look for a bug in my code. Essentially my dynamic object pos...
