Thanks for the help. That all worked, more or less out-of-the-box, using QUAD_BUFFER. As suggested, we had to enable stereo in the OpenGL driver.
I was slightly misinformed about the actual hardware, what we are actually using is this : http://www.vuzix.com/iwear/products_vr920.html, which also uses a field sequential sort of stereo. LIke I said though, all works OK. Out of curiosity, in a couple of our apps we set various features of the views e.g. window sizes (via graphics context traits), projection matrix resize policy and so on. For anaglyphic stereo mode, this was all fine, but in quad buffer, we got lots of OpenGL warnings. Turning a big set of methods off fixed them in the short term, but lost some functionality; in the long term we'd like to fix this.Are there things that one shouldn't do in quad_buffer that are OK in other stereo modes?
