All:
Can anybody tell me what the maximum Horizontal & Vertical FOVs
(in degrees) for a single channel? I'm using a Horizontal FOV
close just short of -45° to +45°--about 88° total.
The problem I'm facing is some very unusual behavior with the
near clipping plane values. A near clipping plane value of 10
meters causes extreme compression ("scrunching") of the image
along the gaze vector; 2 meters causes compression of the image
to be compressed by about 0.5x estimated; a value of 0.5 meters
causes the image to be stretched out into the distance. All the
above with a far clipping plane of 1000 m. Traversal time for
some distance thru the database is the same regardless of near
clipping plane value, causing very different perceptions of
speeds (driving simulator) depending on the near clipping
value--an unhappy situation.
I'm looking for answers and would appreciate any help or insight
anybody has. Having working with several IGs over the years I've
never seen this type of behavior.
TIA,
Pete
