In order to invert a rotation by unit quaternion q followed by a translation v, you apply a rotation by unit quaternion q' followed by a translation v' where: q' = ~q (conjugate of q, ie. inverse of rotation q) v' = -~q v q (transform of -v by the inverse of rotation q) If you only do translations and rotations, it is ...

Web1 de fev. de 2024 · The root cause of the problem is that OpenGL matrix operations postmultiply onto the matrix stack, thus causing transformations to occur in object space. To affect screen space transformations, you need to premultiply. OpenGL doesn't provide a mode switch for the order of matrix multiplication, so you need to premultiply by hand.
