C(x) = qx¯q is a rotation in the plane orthogonal to u through an angle 2θ. More  The factors are “isoclinic” matrices. In both the Euclidean plane R2 and the hyperbolic plane H2, a non-trivial group of rotations has a unique fixed point. Whichever the order of their composition will be, the "  A Rotation of Cubes. Composing two rotations results in  When we apply a sequence of rotations in three dimensions and then calculate the resultant total rotation we find it follows laws which may not be intuitive. For instance, points h and t lying on  A double rotation where both rotations are of the same angle is called an isoclinic rotation. I have attempted here to give a a bit more explanation of my recent 4D rotation animations, in as non-technical a way as possible. 1.
