PDF: Optimization Strategies for Real-Time Rendering of Virtual Scenes on Heterogeneous Mobile Devices

Abstract

Increasing numbers of VR applications are being developed for mobile devices. Due to the various hardware limitations of different mobile devices, the amounts of data for virtual scenes need to be restricted if one seeks to still obtain fast rendering and a real-time interaction experience. To alleviate this problem, this paper proposes novel optimization strategies for real-time rendering of virtual scenes on heterogeneous kinds of mobile devices with diverging processing abilities. In particular, we deploy a virtual scene around an editable roaming path so as to reduce the arrangement of invisible virtual objects, and optimize the scene layout in the design stage. The virtual objects are bounded with respect to the roaming path, such that the system can render the virtual scenes in the roaming stage in real-time. Our experiments show that these strategies can be adaptively applied for different smartphone devices, operating in larger-scale virtual scenes constructed in advance.
