Flexible Pixel Compositor for Plug-and-Play Multi-Projector Displays

Abstract

In summary, we are developing the next generation compositor to satisfy the demanding needs from emerging applications. It can be used beyond multi-projector displays. The first is auto-stereoscopic (multi-view) displays, in particular lenticular-based displays. These 3D displays in fact display many views simultaneously and therefore require orders of magnitude more pixels to provide an observer adequate resolution. This can be achieved only by a rendering cluster. Furthermore, images from the rendering nodes typically need to be sliced and interleaved to form the proper composite image for display. We also envision that our flexible hardware can be used for distributed general-purpose computing on graphics processor units (GPGPU). It provides the random write capability missing in most current graphics hardware. By providing a scalable and flexible link among a cluster of GPUs, they can efficiently work in concert to solve problems, both graphical and non-graphical, on a much larger scale.
