The least effort approach is to use a program that does that for you. :-) I believe the LiveGraphics Java applet by Martin Kraus does that automatically. In the first example on this page www.vis.uni-stuttgart.de/~kraus/LiveGraphics3D/examples/molecules.html I can select the molecule and zoom in it, until I see the atoms closer to the POV bigger than those farther away. If I remember correctly, the primitives used are simple Point[] statements with a fixed size -and color- for each type of atom. cheers, Peltio
