Abstract / Description:3D display technology holds great promise for the future of television, virtual
reality, entertainment, and visualization.
Multiview parallax displays deliver stereoscopic views without glasses to
arbitrary positions within the
viewing zone. These systems must include a high-performance and scalable 3D
rendering subsystem in order
to generate multiple views at real-time frame rates. This paper describes a
distributed rendering system for
large-scale multiview parallax displays built with a network of PCs, commodity
graphics accelerators, multiple
projectors, and multiview screens. The main challenge is to render various
perspective views of the scene and
assign rendering tasks effectively. In this paper we investigate two different
approaches: Optical multiplexing for
lenticular screens and software multiplexing for parallax-barrier displays. We
describe the construction of largescale
multi-projector 3D display systems using lenticular and parallax-barrier
technology. We have developed
different distributed rendering algorithms using the Chromium stream-processing
framework and evaluate the
trade-offs and performance bottlenecks. Our results show that Chromium is well
suited for interactive rendering
on multiview parallax displays.
