Hello, Upfront I need to say I'm using a modified version of jBullet (which is itself based on Bullet 2.72) with double precision enabled. I've basically done a search and replace on every float -> double, Vector3f->Vector3d and etc. I've grepped through the native source code of Bullet to make sure...

Ah, I think I'm unto something. The two objects I'm linking have collision shapes of type BvhTriangleMeshShape which extends TriangleMeshShape, which (rightfully) does not know how to calculate its inertia tensor. public void calculateLocalInertia(float mass, Vector3f inertia) { // moving concave ob...

Hello, I'm trying to use a Point2PointConstraint between two objects in my game. For some reason, whenever I do, the objects just get completely stuck. One object is much more massive than the other (1000x). If I understand properly the way Point2PointConstraint is supposed to work, using it with a ...

Hello, I'm using the java port of Bullet Physics (jBullet) for a game I'm making. I'm trying to move a bunch of bodies by simply calling body.setCenterOfMassTransform with a transform that has been translated (no rotation here) by the same amount for all bodies. Problems occur whenever I try to do t...
