マルチコンピュータシステムMC - 1における画像生成手法Image Generation Method in Multicomputer System MC - 1jpnhttp://id.nii.ac.jp/1001/00039184/Technical Reporthttps://ipsj.ixsq.nii.ac.jp/ej/?action=repository_action_common_download&item_id=39184&item_no=1&attribute_id=1&file_no=1Copyright (c) 1985 by the Information Processing Society of Japan松下電器産業(株)無線研究所松下電器産業(株)無線研究所松下電器産業(株)無線研究所松下電器産業(株)無線研究所松下電器産業(株)無線研究所日高教行平井, 誠中瀬, 義盛浅原, 重夫鷺島敬之The image generation method in multicomputer system MC_1 is described. MC_1 has a root computer and many node computers and each node computer consists of a 16-bit MPU and an APU which can perform 24-bit floating point operations at the speed of 12 MFLOPS. The algorithm based on Z_buffer hidden_surface algorithm and ray_tracing algorithm can generate efficiently real 3_dimensional images considered shadow reflections and transparency. Some speed_up techniques are adopted such as shadow preprocessing dynamic computational load distribution by computational load prediction of each block (a division of screen area.) Furthermore the algorithm can handle directly polygons and quadratic curved surface.The image generation method in multicomputer system MC_1 is described.
