Abstract

Portals have many applications in the field of computer graphics. Recently, they have found use as a way of artificially increasing the available space in a virtual reality (VR) environment. In this paper, we will cover a technique for making the transition through a portal unnoticeable to the user. Additionally, we will measure the performance impact of rendering portals in a test scene and provide some insight into possible optimisations.
