Thanks for the example, which contains some nice tricks I'll keep in mind for some other application. But I don't see a way to use this for my molecules, because I am need 3D plots. What I really want is spheres. If I draw my own parametric circles in 3D, I'd have to take into account the view point and compute projections. I did play with the idea of defining spheres as 3D surfaces, but I'd expect this to be much too slow. Konrad ____________________ Racket Users list: http://lists.racket-lang.org/users
