Description Tomi Pieviläinen 2012-04-01 05:40:25 UTC
What would it take to support stereoscopic output on newer AMD GPUs, either on HDMI or DP? It seems like it's not limited to DirectX, but also OpenGL works on Windows.
Comment 1 Alex Deucher 2012-04-01 06:12:20 UTC
There's not a whole lot of changes on the driver side; you basically just tell the monitor you are sending 3D (packed 3D is probably the easiest to start with).  However, there is a substantial amount of work required in the rest of the open source stack in general to support 3D displays:
- each frame needs to be rendered twice with different viewports or use geometry shaders to do something similar
- need infrastructure to enable/disable 3D display rendering modes
Comment 2 Tomi Pieviläinen 2012-04-01 06:41:45 UTC
SW-side certainly is not trivial, but for example being able to view prerendered 3D content would be good (stereoscopic blurays being the mainstream example).

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
