Hello, Each point would be a polygon, and you would set the color like for any polygon. This is not very useful for many points on the surface of the sphere because it takes a lot of memory. I would use POVRay years ago to put a texture map around the sphere with the right image of the function. You could evaluate the integration at all the points in mathematica then take the data into POVRay as an image map. Maybe this isn't necessary with the newer versions of mathematica. Bla?

I've used ColorFunction and MeshFunctions before, but they seem to work only on analicial functions, my function is numerical integration in given point and returns a number. Is there any way to plot that kind of graph (colored sphere depending on a value) or can anybody suggest other ways to represent this. > > Thank you, > > Bla=C5=BE Kranjc > > >
