  spherical height map? (Message 1 to 2 of 2)

I'm trying to make a render of some data that will vary in amplitude over
azimuth and elevation (longitude and latitude). Is there a way to make a
spherical height map? Something like r(lat,lon) = x, so the radius at
lat,long on the sphere's surface would be equal to x.

I know I could use many many splines, but is there an alternative?
