I have a problem, and I was wondering if someone out there in Performer Land
might be able to help me. I have a modified version of perfly I'm trying to
run on a Onyx2 iR (64 MB Texture Mem). What I'm trying to do is place "movie
textures" on an arbitrarily loaded object. For simplicities sake, the single
loaded object will only have one texture already specifed on it when loaded. I
attempt to strip off the currently loaded texture and replace it with a
sequence of textures that form a movie. My coding is far from complete, but
I've already hit a snag that I can't get past, and I'm hoping someone out there
can help.
I believe that my texture list is being created/loaded properly, but when I get
to the point where I am to apply the first frame of this new texture list, the
program bombs. Here's what I get:
monet 47% perfly -W640,480 -Tscriptfile2.txt
PF Info: All 4 processors available on this machine.
Loading Script File...
Loading tex flip_simpearthgrid.0000.rgb as frame 0
components: 3 xsize: 1024 ysize: 512 zsize: 1
Loading tex flip_surf_image.0000.rgb as frame 1
components: 3 xsize: 1024 ysize: 512 zsize: 1
Movie List Length: 2
PF Fatal/SysErr: _pfDirtCheck: pfRealloc of 0 bytes returned
NULL.
I'm attaching the part of my source code where the problem seems to be
occurring. I'm also attaching a hardware inventory for those of you who like
to know what kind of system I'm working with.
Any help on this will be greatly appreciated! I will even take recommendations
on where else I might be able to look for more information on movie/video
texturing. -Or if anyone out there has already done something like this,
PLEASE let me know. I'm aware of sample codes movietex and texlist, but
haven't been able to find anything closer to what I'm trying to do.
Thanks in Advance!!
