[PyMOL] POVRay output

[Armand Tepper]

Dear all,

I am a new user of both pymol and this email list so I
apologize when the items below already have been
discussed earlier. I like the graphic output of the
program very much! I am mainly interested in
generating POV output files from Pymol instead of
using the built-in renderer. Regarding this, I have
two comments:

1) In a future version of Pymol, would it be possible
to parametrize the POVray output such that all
textures, finishes etc. are declared once as variables
(e.g. something like #declare carbon_texture =
texture) ? Now the textures are defined for every
primitive (atoms, bonds, triangles) individually,
making changing image appearance a heavy search and
replace job.

2) when the Pymol built-in image rendering is used,
the slab/clipping of the current view is used for the
rendering. Instead, the POVray output includes the
whole object regardless of the part that is clipped in
the Pymol view. Are there any workarounds for this?

Thanks for the help,
Armand

I'd like to second this. It would make editing easier, although
I have found it possible to do with vim as long as I pick easily
distinquishable colours for the different parts of the image.

I'm not sure that I agree with this, but then when I want to use POVray
I'm not simply wanting to render what I can see in the PyMOL view, since
I find the PyMOL rendering sufficient for most normal images.  But
this is simply my opinion.  :)

Cheers,
Robert
