Dear CCL Netters,

For randomly *and* uniformly distributed points on a sphere, 
i.e. random directions over 4\pi as we need them for the 
simulation of scattering processes, we use a uniform distribution 
over \phi (0...2\pi) and cos(\theta) (-1...+1). (Remember the 
constant-scale surface element d\Omega = d\cos(\theta)*d\phi .)

I have read about the regular 60 and 92-point solution with great 
interest. Thanks for that information to Bingze Wang!

The unedited collection of earlier responses to that FAQ offered
by John Rupley I would appreciate.

Sincerely yours,

Wolf Weyrich.
