i'm a newbie to animation with pov, and i have to render big scene files. My
problem is that at any frame the whole scene files are parsed (that takes a
very long time). Is there a way to keep in memory the files that describes
geometry that didn't change during the animation??

thx

Earlier versions of MegaPOV had the ability to have objects that
persisted between frames, but this has never been part of the official
release. The facility was dropped in MegaPOV 1.0 when MegaPOV got
rewritten based on the POV 3.5 sources, and I don't think it's been made
available since then.

Take a close look at what's happening during all that parsing. If the
time is being taken up by complicated calculations, then you can arrange
to have the calculations only happen during the first frame, and write
the source for resulting objects out to a temporary file. If, however,
the reason for the paring taking a long time is that it's reading vast
amounts of object data and not doing much calculating, then there's
probably nothing you can do.
