Abstract
The Ray Tracing algorithm produces realistic high quality images, but it requires a long time of calculation on a single processor machine, which limits its practical use. With the development of distributed objects architectures, such as CORBA (Common Object Request Broker), the most promising way to improve ray traced pictures productions seems to be parallelisation which offers both increased CPU power and memory facilities. A natural way of parallelisation is to distribute pixels over the CORBA objects system. However, since we want to deal with large scenes and making our algorithm functional over any parallel architecture system, scene processors (CORBA objects) according to their speed objects have also to be distributed among processors, so a modified parallel algorithm is necessary. We propose a new method, which distributes the scene objects among frequencies, which uses the object coherency property. Our approach of exploiting the bus CORBA gives very encouraging results.
