Hi,

I found functions to convert between quaternions and Euler angles. And there is a function to convert quaternions into rotation matrix. Is there a function to convert a rotation matrix to a quaternion?

You may find these links helpful. They are not Bullet-specific though.

Only Euler <-> Quaternion conversions are exposed in PyBullet, not the Matrix <-> Quaternion yet.
