We are very happy to announce that today (18th of Jaunary 2012) we have made a first successful projection of synchronized video playback on our system. The video is available here: http://youtu.be/wPJuTTcMCpI (low resolution - filmed with Nokia N80's camera). We have also corrected glitches mentioned in last news.
So, the system now does the geometric transformation of images in real time using NVIDIA GPUs. Since one computer plays video on only two projectors and we have 6-projector system, we need to synchronize the video playback of 3 computers so that they always show the same frame. This is achieved using combination of NTP protocol and our own synchronization algorithm.
