Abstract

Stereo and Multi-View rendering of three-dimensional virtual environments can be accelerated using modern GPU features such as geometry shaders and layered rendering, allowing multiple images to be generated in a single geometry pass. These same capabilities can be used to generate the multiple views necessary for co-present multi-user projection environments. Previous work has demonstrated the feasibility of applying such techniques, but has not shown under what circumstances these techniques provide increased or decreased rendering performance. This paper provides a detailed analysis of the performance of single-pass stereo and multi-view generation techniques and provides guidelines for when their application is beneficial to rendering performance.
