applyTorque and applyForce not working as expected (JBullet)

Post by mattb »

When I use applyTorque, I'm getting unexpected results. Since applyForce calls applyTorque, applyForce is producing unexpected results as well. Here's what I'm seeing:

applyTorque(new Vector3f(10f, 0f, 0f)) - object rotates around global y axis. Expected rotation around global x.
applyTorque(new Vector3f(0f, 10f, 0f)) - object rotates around global x axis. Expected rotation around global y.
applyTorque(new Vector3f(0f, 0f, 10f)) - object rotates around global z axis as expected.

Looking through documentation, demos, forums, etc, I have found very little information about applyTorque. Is the above behavior expected, or is there a bug somewhere?

I am using the latest version of JBullet.

Thanks in advance for taking the time to respond, and thanks to all contributors to Bullet / JBullet.
