C3D is both a collaborative application and a distributed raytracer: users can interact through messaging and voting facilities in order to choose a scene that is being ray traced using a set of distributed rendering engines working in parallel. Near-linear speedup is achieved with up to half a dozen rendering engines running in parallel and communicating using ProActive.
