Stereo 3D in OpenGL applications
Hi.

I'm part of a development team currently working on an OpenGL application and we are looking into stereoscopic 3D. The HDMI 1.4 standard has support for S3D with frame packing in 1080p@24Hz and 720p@60Hz which might be sufficient for our needs.

So, say we have a HDMI 1.4 capable graphics card, monitor/projector and 3D Vision glasses + emitter and I want to do frame packing in 720p@60Hz.
Is it possible to get a 1280*1440 back buffer and fill it manually with the left and right images, swap buffers at 60Hz and have the monitor display it correctly?

I've found it hard to find any information if this kind of manual S3D rendering is possible so any information or hints is very welcome.

If this is not possible are there any other similar ways of getting S3D or is the quad buffer approach the only option?

You need a Quadro card for OpenGL support.

What type of application are you developing?

We are developing a 3D simulation for training purposes and wanted to try S3D for more realism and depth.

Our rendering is based on deferred shading and uses quite a lot of post processing, so a manual approach to S3D seemed like the best option, compared to trying the automatic S3D with the 3D Vision driver.

I work on identicla problem. We need to make Quadro 4600 FX card working with Acer GN245HQ 3D monitor. The monitor have build-in IR emmite rbut the Quadro card doe snot activat it. The reaosn is probably HDMI 1.4 based communication with the monitor. Any help welcome. Michal

I've posted in other areas of the forum.

I'm working on Ubuntu 11.10, though any linux will do.

In a nutshell i'd need one of your Quadro cards that supports OpenGL QBS rendering to be able to output 720p/60Hz frame packed 3d over HDMI 1.4a to my Sony HMZ-T1 (which you recently got working with your geforce cards from what I understand)

I dunno if your Quadro boys have got that working already, but if it's necessary to talk to them, i'd be all over that.
