Greetings,
I'am using PVMegaPOV for rendering animations and it loks like there
is some memory leak: as it computes more and more frames is takes more
and more memory. It is very unhappy, because I use some machines with
64MB RAM and animation, which has at the begining several MB in RAM can
easily use 100 or 200 MB of RAM when computing 100th frame, for example.
Regards
Disnel

I believe all the current versions have this leak. I think the only
thing you can do is render a certain number of frames and restart POV.
Which means you can't have it render while you're gone too. :(

Well, if your sys admin is like the one we had at school, you just won
your ticket for a free, 2 hours long speech about Good and Evil. Sorry
;-)
About your problem, could you first give me some more clues (of course
pvmegapov and pvm versions, and OS as usual), and tell me is you get the
same ting with the old pvmpov (after povray 3.1g), and (as was
suggested) with megapov itself?
I used to have problems with the whole scene being added to the object
list instead of replacing it with an old version.
Bye!

No problem, I was there for two weeks and now I'am using machine with my
configuration and big swap ;-)

pvmegapov 010311, pvm 3.4.3, OS Linux RedHat 6.2.
I don't remember about old pvmpov, but I think, that it had similar
problem....
Practial example: this scene
background {color rgb 0.7}
torus {
10, 1
pigment {color rgb <0.5, 1.0, 1.0>}
finish {ambient 0.3 diffuse 0.7}
}
sphere {
<0, 2*sin(10*pi*clock), 0>, 3.0
pigment {color rgb <1.0, 0.5, 0.5>}
finish {ambient .3 diffuse .7}
}
camera {
location <-30, 40, -30>
right <1, 0, 0>
up <0, 1, 0>
direction <0, 0, 1>
angle 30
look_at <0, 0, 0>
}
light_source {< 100, 100, -50> color rgb 1.0}
light_source {<-100, 100, -50> color rgb 0.3}
