A Novel Control Mechanism for Distributed Stream Rendering

This paper describes a new control mechanism for distributed rendering. Control mechanisms have previously been widely used in many fields from autonomous robots to video streaming. Their use in video streaming has allowed quality-of-service, user orientated, transmission of videos across changing transport networks. We show how control mechanisms can be applied to distributed rendering to provide responsive, user orientated visualisa- tions. The control mechanisms are implemented as an extension of Chromium, a stream processing framework for OpenGL. The system should also be applicable to other stream based render systems with a significant benefit. The new system allows distributed rendering to be modularised into specialist units that self organise work load to meet the demands of the user.
