Octahedron Environment Maps

Download www.vis.uni-stuttgart.de

In this paper, we examine the octahedron as a parameterization scheme to represent environment maps in real-time rendering applications. We discuss two projection schemes and show two convenient unfold mappings to pack the platonic solid into quadratic or rectangular textures. We carry out an analysis and consider rendering performance for interactive applications as well as the quality of representation. We further discuss applications and scenarios which benefit from this parameterization.
