The HiQoS Rendering System
by T.Plachetka, O.Schmidt, F.Albracht
Abstract:
The simulation of the global illumination in 3D scenes is a computationally
expensive task. One of the goals of the project HiQoS (High Performance
Multimedia Services with Quality of Service Guarantees) was to develop and
test a prototype of an e-commerce system which simulates realistic lighting
of large scenes on high performance parallel computers. The system, although
tailored to the needs of this specific application, is very generic and
exhibits metacomputing features: 1.the access to the high performance
computers is fully transparent to the user; 2.the modular architecture of
the system allows to dynamically add or remove computing resources in
geographically different computing centers. The prototype of the proposed
system was evaluated in the industrial contexts of architectural
visualization and film production. This paper summarizes scientific and
technical problems which arose during the project as well as their solutions
and engineering decisions.
