Write the <x,y,z> vector and radius to a file.
Read in the values, generate a sphere of that radius at that point.

Points for style would be to figure out where the camera should be located to
make sure all the spheres are in the raytraced image.

This has been covered before, and I replied rather frequently to Ari -
