3D Stereo Operations
OrthoEngine 3D Stereo is an add-on module to OrthoEngine Airphoto Models, Satellite Models, High-Resolution Models or RPC and Generic Models. OrthoEngine 3D Stereo offers advanced tools for 3D viewing and feature extraction (vector editing) of stereo airphotos, digital camera frames, ASTER, IKONOS, IRS, SPOT, or SAR imagery. For more information visit our Geomatica Ortho Engine 3D stereo page.
What mouse devices does 3D Stereo support?
What are the monitor specifications for OrthoEngine 3D Stereo?
I have airphotos that are oriented South facing up. Can I use these for 3D feature extraction or do they need to be rotated so that North faces up?
Q: What mouse devices does 3D Stereo support?
A) Supporting individual hardware devices specifically would mean building individual drivers for each device. The drivers are significantly different, making this a nearly impossible task.
As long as the mouse device has a Microsoft driver that supports mapping of various keys or functions to the buttons on the device, it will probably work fine (some mouse devices don't conform to Windows mouse functions, even though they have a Windows driver).
We do not provide software-specific support for all 3D mouse devices. However, all of the functionality of the 3D interface is available through keyboard shortcuts, including Function Keys and other assigned functions such as PageUp, Esc, Space, etc. The Geomatica help pages contain a table listing the keyboard shortcuts and their associated functions

Q) What are the monitor specifications for OrthoEngine 3D Stereo?
A) The monitor you choose should support at least 100Hz to 118Hz at the working resolution. For working resolution, we suggest a minimum of 1152x864, though 1280x1024 is a much better desktop size for today's nice 21" monitors. The following list supports those resolutions (according to manufacturer specs):
NuVision Stereo Monitors
Dell Ultrascan P1110(tested)
Compaq P1210(untested)
Viewsonic GS815 (untested)
NEC Multisync FE1250, FP950, FP955, FP1350X, FP1355, FP1370,
FP1375(untested)
Mitsubishi Diamond Pro 920, 9060uNF (untested)
This doesn't mean other monitors won't work. Just check the refresh specs to make sure.
Please also note that some older monitors do not officially support stereo or high resolutions.

Q) I have airphotos that are oriented South facing up. Can I use these for 3D feature extraction or do they need to be rotated so that North faces up?
A) You can use your south up oriented images in 3d feature extraction; however when you create your epipolar images, you need to reverse the left and right images. For example, your left image for epipolar creation would actually be the right image.
You can also rotate your images so north faces up in the Data Input processing step.
