Abstract

In this paper, we present a stereoscopic rendering based on a mobile ray tracing GPU. Adopting an existing algorithm to new mobile GPUs specialized for ray tracing enables two high performance techniques such as reprojection and tile-based rendering. Experimental results show that our implementation can be a versatile solution for future virtual reality applications, as it achieves up to 1.64 times better performance and 20% better energy efficiency compare with state-of-the-art solutions. To the best of our knowledge, our solution is the first to demonstrate mobile virtual reality based on real-time ray tracing.
