    Subdivision of 3D space based on the graph partitioning for parallel ray tracing
    (Springer, 1994) İşler, V.; Aykanat, Cevdet; Özgüç, Bülent; Brunet, P.; Jansen, F. W.
    An approach for parallel ray tracing is to subdivide the 3D space into rectangular volumes and assign the object descriptions with their related computations in each volume to a different processor. The subdivision process is critical in reducing the interprocessor communication overhead, and maintaining the load balance among processors of a multicomputer. In this paper, after a brief overview of parallel ray tracing, a heuristic is proposed to subdivide the 3D space by converting the problem into a graph partitioning problem. The proposed algorithm tries to minimize the communication cost while maintaining a load balance among processors.
