POVSCRIPT

Povscript is a program which reads in parameter files for molscript and writes out instruction files for POV-ray. Online documentation is available, and recommended as more up-to-date.

The above is a colored model of the protein "ras" created by povscript. It was made by the following steps.

First, setup variables and paths:

setup povray (or source /srv/local/setup/povray.set)
setup povscript (or source /srv/local/setup/povscript.set) 

Now make the molecule-specific povray input file:
cp /srv/local/povscript/examples/ras_shiny.in .
cp /srv/local/povscript/examples/ras.pdb .
molscript -in ras_shiny.in -povray -out ras_shiny.pov

Now use Povray to generate the image:
povray +A +V +Iras_shiny.pov +FN16 +W600 +H600 +Oras_shiny.png

• +A turns on antialiasing
• +V turns on verbose output
• +FN16 selects PNG output with 16-bit color
• +W and +H select the resultant width and height of the image

Dan Peisach has written a short primer on POV-ray files.
