MAVERIK is a publicly available virtual reality (VR) system, which has been under development by the Advanced Interfaces Group since 1995. MAVERIKenables rapid production of complex virtual environments as well as providing many functions that are valuable to anyone developing applications with 3D graphics or using 3D peripherals. MAVERIK deals primarily with graphical and spatial management, and integrates with our other VR system, Deva, which extends MAVERIK abilities to multi user and multi application virtual reality. Within this wider context, MAVERIK is designed to support high-performance rendering, including large-model processing, customised representations of environments for different applications, and customisable techniques for interaction and navigation. Although it is a component of a larger system, MAVERIK works equally well stand-alone and forms an ideal platform for the construction of VR applications for individual users.
