[IMP-dev] "smart" orientation grid search

hi all,

Has anyone implemented a function that generates a set of grid search orientations ? something like: IMP::algebra::Rotation3D rotation_grid_search(IMP::Float distance);

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.

thanks, Keren.
