this is not for random sampling but grid search sampling.
Few such needs are for local exhaustive rigid fitting, local binding
refinement, 2D projections and more.

I forgot to say, you only want to return points in half the 4D
sphere if you are trying to even out the sampling (if you are just
random sampling, then it obviously doesn't matter).

yes - i meant that it would return Rotation3Ds

I don't understand what you are looking for. It sounds like it
might be an even sampling of the set of rotations but your
prototype below only returns one rotation...

hi all,
Has anyone implemented a function that generates a set of grid
search orientations ?
We have sphere based and cylinder based rotation sampling, but it
seems that there are better ways (quaternions based) that
maintain a fixed "distance" between all pairs of orientations.
