Stereoscopy error (windows / nvidia)

General TouchDesigner Discussion

I want to try the OpenGL stereo example explained here: OpenGL Stereo | Derivative

I have a Windows PC with a Nvidia Quadro P6000. I followed the steps outlined in the link and opened the example patch with the correct environment variable. The window node shows an error saying “Stereo was not properly setup. Ensure stereo is configured properly in the Nvidia/AMD control panel”.

Of course it is set up correctly in the Nvidia panel, and using a custom software I have written in C++ I can use the quad-buffered OpenGL stereo with active shutter glasses. But something makes TouchDesigner unhappy. Any ideas?

Hi @peterho,

can you let us know what build of TouchDesigner you are using for us to try to reproduce the issue?

Thanks

But I realized that TD now uses Vulkan instead of OpenGL - Vulkan | Derivative

So the page with OpenGL stereo is probably just outdated and not supposed to work anymore?

Yes it’s outdated. There doesn’t seem to be much support for stereo done that way anymore, so it doesn’t seem well supported. I’ll update the help, thanks for the note. If you use newer builds, you get more useful errors at least.
