This article has barely tackled the actual possibilities regarding real-time texturing. Mastering the
multitexturing and texture coordinates techniques is key issue for texture-based effects.
With the generalization of programmable shaders, textures should no longer be seen as images
containing color but as buffers containing information. The interpretation of this
information depends on the use of the texture: color data, normal vectors, various mathematic data
(floating point texture containing for each texel, for example, the square root of each point XY of
the unit disc).
Programmable shaders increase texturing power and flexibility. Before the shaders, only texture combiners
could make it possible to initialize some effects. Now, almost all combinations are possible in a simple manner.
So now guys, unleash your pixels!
