Hi Robert, the problem is that the video card I have has only one DVI output and an S-Video output, so I think they cannot work as two different outputs. Jaime. > Date: Thu, 20 Nov 2008 13:02:28 + > From: [EMAIL PROTECTED] > To: osg-users@lists.openscenegraph.org > Subject: Re: [osg-users

Hi Jaime, The way I would do passive stereo with two projectors is to attach the projectors directly to the two outputs from the graphics card, and then use horizontal split stereo to drive them. The OSG supports this set up out of the box. Using this setup will avoid any need to use quad buffer

Hi everybody!! in my lab they want to re-use an old system composed by a Cyviz Stereo 3D Converter (xpo.2). It basically consists on a splitter which needs a frame-sequencial stereo source, and the output is two videos for two projectors (so passive stereo using polarized projectors & glasses)

Hi Kim, Well, if you "load" a model with its textures, the function will simply return to you a pointer to an already existing model and/or texture (if cache is enabled). Then if all models of your scene share the same texture and/or vertex arrays, I guess (I'm not 100% sure though) this will d
