As default the BARCO projection cubes and graphic channels are assigned in columns from top to
bottom starting with the left column as shown in
some reason. E. g., it may be advantageous to change the order thus, that the channels are assigned
in rows instead of columns as shown in
arrangement

The value is specified in Megabytes. Each AGX G
tem space and 16 MB shareable system space. The shareable 4 MB or 16 MB are made visible to
the CPU through the mapping windows reserved as specified by the MappingCache registry set-
ting.
If other drivers need a lot of system pages or if they are forced to do so by applications there are
two possibilities to make the necessary space available.
On the one hand you can change the set value for the system pages to a sufficient large value. The
system pages entry can be found in the registry under the following path:
HKEY-LOCAL-MACHINE
\System
\CurrentControlSet
\Control
\Session Manager
\Memory Management
\SystemPages
The table below list depending on the operation system the amount of a sufficiently large value for
the system pages.
Operating System
Windows NT 4.0
Windows 2000
Windows XP
On the other hand you can decrease the value for the MappingCache. This can lead to a small loss
of performance for some graphic operations.
