[BUG] Stereoscopic view makes game screen all black

[Anthony-Gaudino]

I'm testing RBDOOM-3-BFG on Linux...

When activated the Stereoscopic 3D (Doom 3 BFG -> Main menu -> 3D Options -> 3D View -> ON) the screen got all black. I closed the program (It was in windowed mode), then when running the game it always was all black.

To solve it, I had to restore this setting from the configuration file (~/.rbdoom3bf/base/D3BFGConfig.cfg) changing the:

set stereoRender_enable from "1" to "0"

and removing the profile (~/.rbdoom3bfg/base/savegame/profile.bin).

My specs

CPU: Core 2 Quad Q6600
RAM: 2GB DDR 3
VGA: Radeon HD 5570 Driver v. 8.84
MB: MSI P35 NEO Combo
OS: Ubuntu 11.04 64bit

PS: Thanks a lot for this port.

Your graphics driver is from AMD and is almost two years old - it's a miracle the game runs at all ;-)

And without hardware that supports stereoscopic rendering (like 3D glasses or something like that?) I wouldn't expect any success with this option, so probably this behavior is to be expected.

[Anthony-Gaudino]

I would expect an error message or the setting being unavailable if my hardware is not compatible.

I just enabled this setting as a test because I really don't care about stereoscopic : )

I will update my driver and see if this helps solving the black screen, and will post the results.

[Anthony-Gaudino]

I updated the driver to the latest version, but the black screen persists.

Well I think this may only work with NVIDIA stereoscopic.

[DanielGibson]

Or if you actually use stereoscopic hardware.
I think fglrx should support stereoscopic hardware, but maybe you need to set things in xorg.conf for that.. no idea.

However, I don't know if there is any (reliable, portable amongst different drivers) way to find out if stereoscopic is supported and appropriate hardware is connected.
If not, we should just rely on the user not activating it ;)

With stereoRender_interoccularCentimeters 0, black screen disapear in menus and 3D works very well but in game I only can see the UI and many OpenGL errors in RenderSystem.cpp line 773.
