WebJun 30, 2024 · Your problem is that you don't understand Quaternions. That's ok. Most people don't. the x/y/z/w components of a quaternion are not angles and cannot be simply treated and manipulated as such. It's better to forget about individual components of Quaternions and use the Quaternion API to do what you need. First off, replace this … WebThe operation ˚r = q˚˚r˚q∗ turns a “purely imaginary’’ quaternion into another purely imaginary quaternion. The inverse of this operation is simply ˚r =q˚∗r˚ q.˚ It is easy to show that the operation preserves dot-products. That is, r 1 ·r 2 =r1 ·r2 where ˚r1 =q˚˚r1q˚∗ and ˚r 2 =q˚˚r2q˚∗.
