Re: Strange behaviour of long rotating bodies

What's your gravity value? If it's around 10, then your objects are absolutely massive - unlike anything you've seen in reality... It is 15, but no matter to what value I set the gravity, bodies still behave the same, except for the fact then everything moves slower of course. I also tried changing...

Re: Strange behaviour of long rotating bodies

Diameter is 0.5, height is 8. The shorter the cylinders (or capsules, I've tested them as well) are, the less the effect is visible.

Re: Strange behaviour of long rotating bodies

@mdias: I'm using cylinder shapes. Here's my code, could the local inertia be wrongly calculated? (d - diameter, h - height, mass is 10) btCollisionShape* shape = new btCylinderShape(btVector3(d/2, h/2, d/2)); btTransform transform; transform.setIdentity(); transform.setOrigin(btVector3(pos.x, pos....

Strange behaviour of long rotating bodies

Hi, I develop an engine and try to use the Bullet Physics Library in order to add physics to the engine. However, the simulation looks very unrealistic when I create some long bodies, such as cylinders or capsules, and make them rotate. They will rotate all the time and will never fall down to the g...
