Abstract
|
We
present a new computer graphics rendering architecture that allows “all
possible views” to be extracted from a single traversal of a scene
description. 
It
supports a wide range of rendering primitives, including polygonal meshes,
higher-order surface primitives (e.g. spheres, cylinders, and parametric
patches), point-based models, and image based representations. To demonstrate
our concept, we have implemented a hardware prototype that includes
a 4D, z-buffered frame-buffer supporting dynamic view selection at the
time of raster scan-out. As a result, our implementation supports extremely
low display-update latency. The PixelView architecture also supports
rendering of the same scene for multiple eyes, which provides immediate
benefits for stereo viewing methods like those used in today’s
virtual environments, particularly when there are multiple participants.
In the future, view-independent graphics rendering hardware will also
be essential to support the multitude of viewpoints required for real-time
autostereoscopic and holographic display devices.
