No, something much simpler. I am talking about taking a cube and inflating
it into a sphere. I found this pic on google:

Of course this doesn't give you as much freedom over how many points you
want, but it has other advantages. I had a macro which split up a sphere
three different ways, but I guess I killed it, because I cannot find it.

I am guessing that by "base-position" you mean the location of the hair
before or after it is wrapped around the sphere. If this is the case, then
the pigment will have to be placed in a 2D pattern which will represent the
sphere "unwrapped." With the inflated cube method, this 2D representation
can be a simple 't' shape if you don't mind just a little distortion. This
method will also return a point set much faster than any other I can think
of.
