By means of ray tracing algorithm, we can render shadows more precisely than those of Z-buffering. We have found that, using simplified algorithms of ray tracing and hardware accelerations of GPGPU (OpenCL), it is possible to use ray tracing to render scenes at operations where real-time responses are required. Using a hybrid method of Z-buffering accelerated by OpenGL and ray tracing accelerated by OpenCL, it is possible to render quickly enough in such situations as changing viewpoint using GUI, and so on.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
