Webcam Stereo Vision Pt. 2

After some more experimentation, it appears that framerate issues come from the image being too dark - doesn't matter if the image is dark because you've set gamma, exposure, brightness or gain, if the image has a very low average brightness, the framerate will plummet, even with 'auto' everything off. I don't recall this happening when I was using just one camera, but that was on a different machine a long time ago.

Because the framerate varies with brightness, and because the brightness changes all the time, the sync issues mentioned in Part 1 are not predictable. Fortunately, the good old "z += (newz - z) / filteramt" 'filter' came to the rescue, and for as long as the cameras maintain a reasonable framerate, things go well.

To be honest, this whole thing would be a bzillion times easier if TrackIR cameras (with their framerate and optics geared towards this task) could show up as VFW devices, but my questions to Naturalpoint regarding that got bounced around internally, then went unanswered. Then again, I suppose they really might not want to talk to me considering I kinda made a competing product. Doot de doo.
