Abstract:
Large-format tiled display is a new emerging technology for constructing large scale，high-resolution, immersive multi-projection virtual environment systems, which can present high-resolution stereo images. A PC-cluster,
five-display-channel tiled display system is built in this paper. It produces a 5120x768 stereo image. The software infrastructure has been designed using a retained mode sort-first parallel rendering paradigm. This paper discusses development issues including selecting on projectors and projection surface to support passive stereo, synchronization tiled displays, geometric correction and color calibration etc. Finally, overall display performance is given and future work is mentioned.
