Obtaining momentum quaternion from two quaternions and timestep
问题 I have a quaternion which holds the rotation of an object. During the frame I modify it and obtain a new quaternion. I can calculate a quaternion that rotates from 'previous frame' to 'current frame'. I cannot figure out, however, how to 'divide by t' this quaternion to get the rotation-per-second that I need. I.e, based on the timestep, I need to know what the quaternion would look like had it been applied to itself an X amount of times (meaning, 28.5 times at 28.5 fps, etcetera). Would
