MULTI-PROJECTOR DISPLAY WALL SYSTEM DRIVEN BY SINGLE PC FOR WINDOWS DESKTOP APPLICATIONS
Large-format high-resolution display systems are increasingly adopted in virtual reality, digital museum, scientific visualization, and other application fields. Traditionally, wall size display system is driven by a cluster of PCs or special high end graphics supercomputer. With the rapid advance of PC graphics hardware, one inexpensive mainstream PC has the power to drive multiple high-resolution displays. In this paper, we propose one multi- projector display wall system driven by single PC. Besides graphics intensive applications, our system can transparently and efficiently display windows desktop applications without modifying the source code. It takes advantage of the bandwidth of PCI Express interface, and supports at least triple projectors, which is suitable for constructing immersive virtual reality center. We also design geometric alignment and photometric correction methods to display the framebuffer content seamlessly on the planar display screen. Experimental results show that our system can achieve real time refresh rates. It does little side effect on the performance of common non-graphics windows desktop applications.
