Many people don’t even know that there were 3d rushes before the one that’s currently fading. In a previous one, some ten years ago, I bought a very expensive ASUS graphics card with shutter glasses. It was really cool for gaming with the 21 inch CRT, but nothing compared to the graphics of today’s games. I still have the glasses, and I wondered many tmes, if I could use them with current equipment. There have been pages on that topic for a long time, but only now I found a page that has all the details to get me interested enough. It features a preload library with which you can hook into the process of switching the image. It has different color schemes as well as sequential for shutter glasses. It uses the V-Sync of the VGA connector to trigger the glasses. But VGA is not so common these days. Luckily, the preload lib is opensource. That allowed me to modify it so as to communicate to an Arduino or orher micro controller through USB FTDI.
