Distributed rendering on grid computers for multiple users in shared virtual space

With the continued increase of communication speeds and improvements to edge computing environments, server-side rendering is once again attracting attention due to the diversification of user terminals.There are a few new structures that can be scaled in accordance with the number of users. However, in the case of applications where many people share the same 3D space in real time, the number of unique models and the inherent complexity of the models uploaded by users make it difficult for cloud-based rendering systems to handle such applications.In this paper, we introduce a new image-based distributed rendering architecture that allows multiple clients sharing a space to receive rendering results. Further, we reduce the throughput with data compression and add realism with shadow effect. Finally, we report the measurement results of one system based on our architecture using the grid computers TSUBAME 3.0.
