Contours of a real-valued function on sphere

Hi, Thanks for this wonderful tool!

Suppose I have a function f that maps the points on the unit sphere to real numbers. Is there a way to draw several contours of f on the unit sphere? for example, f(x,y,z) = c for some constant c = -1,-0.5,0,+0.5,+1 where x^2+y^2+z^2 = 1.

Thank a lot.
