Hi,
I'm trying to build an application for terrain visualisation used in flight
simulation. As i have to cover a large area,
the database is made up of several (together about 8000) tiles. I started
from perfly code, added a database function
in a separate process which should handle the paging of the tiles.
Loading the tiles works fine, but deleting the tiles with an pfAsyncDelete
() consumes increasing time. As a result old tiles
are not deleted fast enough and the new tiles, which should become visible
are not loaded.
My hardware is a dual pentium with 2x2GHz and GeForce4 4600Ti Graphics
Card, running Suse Linux 7.3 with XFree 4.2
and latest NVidia drivers. Performer is installed as evaluation copy.
On a similar hardware with nearly identical system (but licensed
performer), just slower processor, everything works fine.
Is there some restriction to the evalutaion version running without license
?
Ore are there any other hints, maybe some code examples for building and
running a multithreaded application with paging ??
Any help is welcome
