We are flying around a relatively large database that was created from
DTED data. The database has been translated to its correct lat lon position.
The problem we have is the X,Y,Z numbers are so large, the image seems
to jitter eventhough the eyepoint is stationary. I would appreciate any
existing solutions or workarounds.
Thanks
