Active stereo does not work
I am using the 1.5.1 branch + processing 1.5.1 on ubuntu 12.10 32 bit, NVIDIA driver 304.88 (Quadro K5000). The ActiveStereoTest example does not appear to work. It just shows the perspective of one eye and the IR emitter does not even light up. The following error is shown in the console:
OpenGL error 1282 at top endDraw(): invalid operation
cheers, Rob
Hmm, the 1.5.1 branches ActiveStereo should work. I even tested it on Nvidia Quadros (I can't remember which one). I'll look into it. Also, the newest version of Processing 2.1 should enable access to the GLCapabilities which will let me try out active stereo (it was hidden in on P2.0). Thanks for filing the errors.
it would be really great to have it working with processing 2.1! i quickly tried to branch processing (0225) to add a caps.setStereo(true) to PJOGL.java. this will at least trigger the IR emitter and the shutter glasses but i still have not idea yet how to convince processing to render to GL_BACK_LEFT and GL_BACK_RIGHT. one reason for me to use processing is that i don't have a big clue about the opengl stuff :)
cheers, and thanks for the effort! Rob
Hi, we are also having issues with active stereo using Nvidia drivers. Processing 2.2.1 lets us set the GLCapabilities properly, but for some reason the GL_STEREO isn't being activated properly (seems to be a driver issue with our setup, not a Processing issue).
You might want to try and see if you can mimic the 1.5 code in the new 2.2.1 branch (which will be moved to the master branch soon). Let us know if you have any success with your setup. I can send you some test code as well in a few days.
