So parallel computers such as cluster system are usually uesd to generate high quality graphics. In this paper, we discuss on the advantages and the disadvantages of there parallel ray-tracing algorithms; object-base parallelization, space-bace parallelization and pixel-base parallelization. Then we implement the parallel ray-tracing algorithm using pixel-base parallelization into a cluster system that has 44 processors, and evaluate the performance of the parallel ray-tracing algorithm. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2008-08-30 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/1638 https://miyazaki-u.repo.nii.ac.jp/records/2702 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 37 281 286 https://miyazaki-u.repo.nii.ac.jp/record/2702.1/files/KJ00005016065.pdf application/pdf 281.0 kB 2020-06-21
