This tutorial shows how to implement the main techniques of texture mapping using the OpenGL Shading Language. Simple and multi texturing, environment mapping (sphere mapping, dual paraboloid mapping and cube mapping), texture warping, projective texture mapping as well as some examples of special textures such as alpha maps or gloss maps are studied. Several simple demos using the freeware Hyperion Demo-System are provided to illustrate all concepts.
