CalVR: an advanced open source virtual reality software framework

Abstract

We developed CalVR because none of the existing virtual reality software frameworks offered everything we needed, such as cluster-awareness, multi-GPU capability, Linux compatibility, multi-user support, collaborative session support, or custom menu widgets. CalVR combines features from multiple existing VR frameworks into an open-source system, which we use in our laboratory on a daily basis, and for which dozens of VR applications have already been written at UCSD but also other research laboratories world-wide. In this paper, we describe the philosophy behind CalVR, its standard and unique features and functions, its programming interface, and its inner workings.
