Iota Phi Theta Sweethearts
It makes visualization of rotation with Euler angles. phi theta psi are changeable. Also it makes automatic conversion to axis-angle form of rotation. Any rotation can be represented as axis of rotation and angle of rotation. See euler_axis_angle_relationship.doc. Push "rules..." button.See also...

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...
