Tsjerk,
I think you are missing the point of Tom's post, which was a suggestion to
aid someone who's computer could NOT deliver the image in "as high a
rsolution as you want', so Tom was proposing a way to break the image down
into bite-size chunks that the computer COULD then handle. So the suggestion
was to take one scene desired at 9000x6000 which would make the computer
crash and instead mathematically figure the necessary transpositions to
render it in tiles such as upper left quadrant, upper right, etc. each at
4500x3000 or whatever the computer could handle (and then you could put them
all back together in photoshop, e.g.). So for someone with deep coding
skills they could likely teach pymol to ray just the segments they wanted
and deal with the overall perspective of the whole scene, but for a hack
like myself I'd likely start the work around of trying to figure out the
camera position and where I'd have to put it to get just a quarter of the
scene at a time in the viewport (or an eighth, or whatever). As Warren said,
you'd likely have to set orthoscopic to get rid of the perspective for
starters (at least in the hack approach, but there would be more direct
better ways for the skilled).
As a side point, Povray (if I remember correctly) in fact allows you to
break a large rendering job up into tiles pretty much just like Tom
suggests, so not so crazy of an idea! I think in that case you can specify
starting and ending x,y pixel coordinates from your large scene. But not in
Pymol as far as I know.
Sorry if I've now gone stepping in and misinterpreting someone's points
myself, but it seemed like there was a lot of cross-purpose talk either from
assumptions or extra politeness!
