Re: [IMP-dev] IMP::algebra::get_uniform_cover_rotations_3d



thanks Daniel.
you mean that its uniform on patches of the same area on the sphere right?
in that case it might be ok.

If you don't have cgal installed, it just takes n random points uniformly over the upper half of the 4 sphere.If you have CGAL, it smooths them out some.

I'm not sure what you mean by poles (it is uniform over the upper 4- sphere).

hi Daniel -

Frido and I are using get_uniform_cover_rotations_3d for exhaustive
rotational sampling.
The code for this function seems to sample random vectors on a 4D
sphere.
How sensitive is it to poles over sampling?

thanks,
Keren.
