If that's the problem - which was at some point probably my problem, too
- I propose to just create an array of images and not one of pixmaps.
Either you can store them on disc or keep them in memory and display
them with the usual tv or tvscl routines. It works for me. Might be a
trifle slower, but I guess that's the price you pay for large sequences
of images.
I ended up with a routine that pre-processes my images and saves them
individually (I want to display some additional data printed onto them)
and then I call a routine which creates an *.mpg file out of this
sequence of images.
e-mail me, if you need more code details.
Best regards,
Ingo

j is not your problem. You are just running COMPLETELY
out of pixmap memory, would be my guess. :-)
You could try getting a graphics card that off-loads
pixmap memory to the hard drive, but I wouldn't know
which one that is. If you really want that many frames, you
may have to figure out another way to do the animation.
Cheers,
David

Now i understand what the problem is but I dont know how to fix it:
n=100000L
x=findgen(n)
y=findgen(n)
z=findgen(n)
XInterAnimate, set=[500,500,999]
for j=1L,998L,500 do begin
plots, x((j-1):j), y((j-1):j), z((j-1):j),/T3D,/DATA
XInterAnimate, Frame=j, Window=!D.Window
endfor
XInterAnimate
Although j is defined as a 'long' number the number j*100 is not and
the animation stops when the limit is reached..
How do i fix it???
Thanx a lot

You might try to use a long variable as counter:
FOR j=1l,9999l do begin ...
Just a random guess, though.
Best regards,

I'd guess that it means your X, Y, and Z variables
are not 200 times as big as your counter. That is
they are not arrays of size one million.
Cheers,
