This tutorial talks in detail about the normal-map compression and the problems caused by this compression. Various solutions using OpenGL Shading Language shaders are analysed (renormalization, swizzled-DXT5 and ATI’s 3Dc). Several demos using the freeware Hyperion Demo-System are provided as well as an OpenGL project showing the loading of a compressed texture.
