hi, i'm trying to page-flip two incoming firewire cameras (real-time). i have semi-succesfully managed to do it using software page-flip, with the problem that occasionally left and right eye signals are swapped. does anyone know of a way it could be done more accurately using the nvidia drivers, ie. hardware way? tanx | ||

Read Michal Husak's recent paper :- http://www.lightspeeddesign.com/pdf/Lightspeed%20-DepthQ-%20The%20Science%20behind%20DepthQ%20HD%20Media%20Server%20as%20presented%20SPIE%201-19-2004.pdf Basically, you use DirectShow to acquire the signals and quad-buffered OpenGL to hardware display them. Recording AND displaying is not really practical at decent framerates and resolutions. | ||

You can use Stereoscopic Player (http://mitglied.lycos.de/stereo3d) to display live stereo video using the File->Live Video->Stereoscopic Multiplexer command. First, you have to install the Stereoscopic Multiplexer driver, http://mitglied.lycos.de/stereo3d/StereoscopicMultiplexer030.msi. The Stereoscopic Multiplexer is a 'virtual' capture driver that allows to capture from two 'real' devices simultaneously. It combines left and right stream to side-by-side format. The Stereoscopic Multiplexer can be used in almost all video processing applications, not only Stereoscopic Player. For example, you can use it in Windows Media Encoder to broadcast live stereoscopic content. By the way, receiving and displaying stereoscopic Windows Media Streams is possible with Stereoscopic Player :-) Stereoscopic Multiplexer works both with DV cameras and Firewire/USB webcams. In the second case, it's possible to sychronize camera parameters (zoom, focus, iris, exposure, brightness, contrast, color balance, ...) and you can even specify a correction function if the cameras are calibrated differently. For more details how to use this features, please contact me: pwimmer@gmx.at. |
