/*

|
|
3D engines often represent rotations as unit quaternions. These form a three-dimensional elliptic space. What if we could fly through it?
|
|
|
|
Lower left corner shows the rotation matching the current camera position. Beams in the rotation space correspond to bumps on the sphere.
|
|
|
|
Run like:
|
|
[hyper] -geo 2 -rotspace -rot_uscale 0.25 -qtm (space of rotations of the sphere)
|
|
[hyper] -rotspace -rot_uscale 0.25 -qtm (space of rotations of the hyperbolic plane, slow)
|
|
[hyper] -geo Nil -qtm (Nil, which is not a space of rotations, but similar; rendered in a similar way)
