Hi,
This is about the way I do it :) To make life easier, I have a
function to write the POV-Ray file in two pieces, using an #include
statement to include the object description in the overall scene setup
file. I've found this much easier to work with, since it allows to
change the light and camera and such much quicker than editing a
multi-Mb file, and the object description is easily modified with
sed/awk. But what it comes down to is memorizing this one line to
export your (part of a) scene to a POV-Ray include file:
open("part.inc","w").write(cmd.get_povray()[1])
Or to make it even easier:
def writepov(x="povray.inc"): open(x,"w").write(cmd.get_povray()[1])
cmd.extend("writepov", writepov)
Hope it helps,
Tsjerk
