"Euler angle triplets can always be translated into a rotation matrix, and vice versa" -- Well, most of the time, if you neglect the double cover and the singularity (gimbal lock) problems with Euler angles. You can also convert quaternions to rotation matrices and vice versa but you have double cover there too (AFAIK, never used).

WebYes you would, at least not accounting for the earth's revolution around the sun. We tend to equate time with where we are in relation to the earth's rotation (noon being about where the sun is at its highest point, midnight at its lowest) so if you moved to keep the sun at the same relative position, you would keep experiencing that time. Webrotation matrix R is universal to all representations of orientation, including quaternions. The roles of the trigonometric functions, as written, are specific to Euler angles, and to …
WebNov 8, 2024 · This is why transforming a column vector into another column vector requires a square matrix. Let's put the rotation transformations in Equation 3.1.3 into matrix form. Noting that this rotation is around the z axis, so that the z coordinates don't change, we have: (3.1.6) ( A x ′ A y ′ A z ′) = ( + cos θ + sin θ 0 − sin θ + cos θ 0 ...
