An implementation of the ray-tracing algorithm that is based on the Voxar parallel processing model, which simulates 3D physical phenomena, is discussed. The implementation of a general parallel ray-tracing program, and the implementation of Voxar are reviewed. Results of a performance evaluation of Voxar show that the machine's best points are its efficiency on complex ray-tree images and its parallel animation functionality. Its weak points are the insufficiency of the deadlock prevention strategy, the high cost of the communication system, the sequential generation of the primary rays, and the rigidity of the regular subdivision.<>
