i am not a programmer but i am using Performer to visualize
a database of images and texts from the history of photography
as part of my Master's thesis, and i was wondering if anyone
out there has any advice for me...
i am coding in C++ on an onyx, and i am running into what
seems to me like limits in the number of polygons(?) or maybe
DCSs that i can draw. whenever i try to run my code with the
entire contents of my database, it seg faults. when i cut down
the size of the database, it runs without problem.
it seems to load all the texture maps and make all the
graphical objects without complaint, but then when it goes to
draw them for the first time it seg faults. when i tried
switching compilers, it didn't seg fault but it didn't ever
draw anything either.
i know it is not the texture memory, cuz when i try drawing
rectangles in place of the texture maps, it still seg faults.
i guess i have just written some bad code, but i don't know
where to begin to find the problem. why would it work when
drawing 100 items, but not 200? am i reaching some memory
limit that i don't know about, and if so why doesn't it
give me an error message or something?
any help/advice would be greatly appreciated.
thanks!
robin
