Abstract

Normal maps and bump maps are commonly used techniques to make 3D scenes more realistic. Consequently, the efficient storage of normal vectors is an important task in computer graphics. This work presents a fast, lossy compression/decompression algorithm for arbitrary resolutions. The complete source code is listed in the appendix and is ready to use.
