2.3 3D Stereoscopy
To use 3D Stereoscopy in CmME, a compatible hardware and software configuration is needed.
Professional graphic cards supporting 3D Stereoscopy are needed to activate the Stereo Mode, for example: nVidia Quadro/Quadro FX cars or ATI Fire GL cards.
We have tested this with the following devices:
Quadro FX 2000
Quadro FX 3000
Quadro FX 4500X2
At the moment, it is not possible to use regular gaming cards like nVidia Geforce series with CmME. Please keep in mind that also the brand new Geforce cards support only Full Screen 3D Stereoscopy. Correlating this with a GUI like in CmME will surely not work.
Monitors, Beamers and 3D Glasses
Different devices are compatible with 3D Stereoscopy. A wide variety of techniques exist. We tested the following possible configurations with the graphic cards mentioned above:
EIZO FlexScan F980 (CRT)+eDimensional 3D Vision System incl. Shutter glasses
Planar SD2220W (LCD)+Planar Passive Stereo Glasses (Linear Polarization)
Sony Multiscan G420 (CRT)+eDimensional 3D Vision System incl. Shutter glasses
2X Barco IQ-Graphics 300 Beamers+Screen WA2250 Backprojection wall+HNCP37 LH/RH Polarization Filters+Barco Passive Stereo Glasses (Circular Polarization)
Drivers and OS
Please be sure to use the newest stable drivers of your graphic card in combination with an operational system supporting OpenGL. With older graphic cards like the Quadro FX 2000, there are issues known that the graphic card driver is not repainting the GUI elements of one eye correctly. With the newer graphic cards, like the Quadro FX 4500X2 or the Quadro 4000 in combination with the newest drivers, this is no longer an issue.
If you have installed the newest drivers, you have to toggle the driver into Stereo Mode. nVidia drivers let you choose between different Stereo Modes, like Clone Mode for dual displays (like 2XBarco Beamer or the Planar SD2220W) or the Integrated DIN-Connector for CRT displays. In Windows, you can normally do this with the driver software, on Linux you may have to edit the xorg.conf. Please refer to the documentation and the webpages of your graphic card provider. 3D Stereoscopy has been tested with following systems
Ubuntu 10.04 LTS
Finally, you have to tell Java/Java3D that it has to start in Stereo Mode. Please add this to your VM arguments:
For 3D Stereoscopy, OpenGL is needed. Java3D normally always starts in OpenGL, also on Windows. If it starts in DirectX mode because of some strange configuration, please add this to your VM arguments, forcing Java3D to start in OpenGL mode:
The Stereo Slider
If CmME is in Stereo Mode, a Stereo Slider is added to the toolbar. The check box can be used to deactivate Stereo Mode and the slider toggles the eye distance. The settings affect all 3D Views of CmME and provides a realistic three-dimensional impression, especially interesting for the Alignment Mode.
