Hi Ian, As this may be of broader interest, I forward it to the pymol user list too.
You can clip the scene using an intersection. Let's say that you have the object you want to clip stored as a povray include file "object.inc". Then you can get the clipped object as: //### pymol_object = union { #include "object.inc" } clip = ...; // Here you need to fill in the 16th number from get_view(), giving the distance of the front clipping plane intersection { object { pymol_object } plane { z, -clip } } //### The plane could also be defined as plane{z,0 translate -clip} or, along the same lines, as plane{z,0 rotate 30*y translate-clip}. Like that you can have the clipping plane rotated. Do note that such intersections are often very slow. Especially with meshes (like surfaces) it is likely to be a pain (but potentially yielding great imagery :)). With many separate objects, spheres in particular, you can clip each of them separately, which is much faster, especially if you use the directives 'bounded_by' and 'clipped_by'. For a sphere defined as sphere{<0,0,0>, 1 pigment{color rgb 1}} this means that you convert it to intersection{ sphere{<0,0,0>, 1} object{IntersectionObject} pigment{color rgb 1} bounded_by { sphere{<0,0,0>, 1} } } I would suggest scripting this... :) Hope it helps, and good luck!
