[pstricks] Main memory issues with PSTricks

[Christoph Bersch]

Hi,

when I have a document containing around 3500 \pspolygon commands, TeX
complains about exceeded memory:

! TeX capacity exceeded, sorry [main memory size=3000000]

What is so memory-consuming in the \pspolygon commands? Is there any way
to write a special pspolygon command which needs drastically less memory?
The point is that I am currently extending the gnuplot pstricks terminal
driver and the 'set pm3d' command needs a lot of polygons :-)

Thanks,
Christoph
