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.
