Hi All.... newb question.... I'm trying to develop a stereo app that streams video from 2 cameras (left and right). I'm using some NuVision shutter glasses which plug into the VGA output of my motherboard. The glasses auto-sync to each vsync of the CRT and I'm using DirectX's Direct3D features to "Present" my backbuffers on each vsync (D3DPRESENT_INTERVAL_ONE). Everything works well as long as my display thread priority is HIGHEST or TIME_CRITICAL. But, I don't see any way ensure that my left camera image appears in front of my left eye. And, depending on the processor's load, my left and right images reverse on occasion, I suspect because the CPU wasn't processing my thread at the time of the vsync. I see a lot of discussions here about graphics cards. Have I reached the limitation of my architecture? Can I do this with DirectX or do I need a hardware solution? Many thanks, Rob |
