Development of CAVELib Compatible Library for HMD-type VR Devices

Abstract

Head-mounted display-type VR devices (HMDs) are becoming a practical platform for three-dimensional scientific visualization. To reuse software assets that have been developed for CAVE-type VR systems (CAVEs), this paper presents a C++ library for porting CAVE application software to HMDs. Our library emulates the function calls of CAVELib, which is a commercial library for developing application software executable on CAVEs, and it enables us to easily port CAVELib application software to HMDs with minor modifications to the original source code. Sharing the source code also leads to an improvement in the software development efficiency, which is executable on both CAVEs and HMDs.
