Efficient Remote Rendering Using Equirectangular Projection

Abstract

Presenting high quality Virtual Reality (VR) experiences on head-mounted displays (HMDs) requires significant computational requirements. To ensure a high-fidelity experience, the displayed images must be highly accurate, detailed and respond with a very low latency. In order to achieve high-fidelity realistic experiences, advantage needs to be taken of remote high performance computing resources. This paper presents a novel method of streaming high-fidelity graphics content from a remote physically accurate renderer to an HMD. In particular, an equirectangular projection is transmitted from the cloud to a client, so that latency-free 360° observations can be made within a viewpoint.
