Ratboy responds with,
Funny you should mention the media. I had arranged the lights as they were
with media in mind. I wanted a misty colored glow encircling the room with
the bright statue and the string of water like beads shrouding the statue.
It would have been a neat effect. This was rendered at 800x600 with an AA
of 0.3. While a lot of the details are still fresh in my mind I might retry
it but I doubt it will ever be the same as seen now. Might be better who
knows. So many things to try so little life span to do it in.
I have had problems with Pov in the past when hitting memory use in excess
of 100 - 200 megs. My swap file right after the crash was over 250 megs and
add in the physical ram you have a quite a bit to manage. For some reason
somebody in the system gets confused as to who has control over the
operation and the swap file goes into a permanent read/write mode. The only
way to stop is to shut down with the windows task manager. First time it's
ever taken out a 1.2 meg file with it in the process.
I suspect the data loss comes from the way the Pov editor keeps the file
in a memory buffer instead of taking care of everything by reading and
writing to disk. When I had to shut down the program because of a memory
problem, as it shut down it tried to write back to the file to reflect the
current state. Unfortunately the current state was corrupt and it wrote a
0 byte file. If it relied upon the hard drive instead of the memory buffer
it would be a much safer process. This is all of course personal observations
based on conjecture because I haven't a real clue how memory management is
taken care of at a system/program level and have to guess a lot.
