What kind of projection do you think of? You may select one of the
map projections or picture the sphere as a ball using a light source.

You may think of your sphere as of the earth without continents and
oceans and project the colors that represent the diff densities on
that "earth". Is that a way you may want to go?

Map projections are standard transformations in IDL, so nothing to
worry about.
