}Expand description
Spherical-linear interpolation.
Basically, interpolation that maintains a constant angular velocity
from one orientation on a unit hypersphere to another. This is sorta the “high quality” interpolation
for Rotors, and it can also be used to interpolate other things, one example being interpolation of
3d normal vectors.
Note that you should often normalize the result returned by this operation, when working with Rotors, etc!
