I could see how that might happen- persp creates many, many small rectangles which results in a large file size and may operations for the TeX processor to handle. I was able to compile the example you posted, but due to the amount of graphic elements, it took a long time ~25 seconds. If you have the time, do you think you could email me the following feedback:
1. Was it the inclusion of one tikzDevice plot or a series of plots that caused TeX to run out of memory? 2. What was your memory limit? i.e., I'm assuming you got an error similar to: TeX capacity exceeded, sorry [main memory size=X]. What number was X? Thanks very much for trying the package and for any information you have the time to provide! -Charlie On Sun, Aug 30, 2009 at 11:00 PM, Friedericksen Hope < friedericksen.h...@gmail.com> wrote: > Dear Charlie, > > thank you very much for your response.
