Hi,<br><br>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?<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=13436">cttc</a> — Sat Oct 05, 2019 2:06 pm</p><hr />
