How do you describe to someone the difference between textures, shaders, and materials. Or is this three words to describe the same thing?

Surfaces are the names given to polygons so that you can apply basic surface parameters (i.e., color, specularity, bump), to them, as well as textures and shaders.

Textures add to the tactile appearance of a surface by giving it the illusion of Multilayered images on a surface are examples of textures. Materials is the term for textures in other apps.

Shaders alter the rendering algorithym and thus dramatically affect how surfaces look when rendered based on the lighting in the scene, as well as the quality of surface shadowing. Parameters such as angle of incidence to the camera or to light sources in the scene help to determine the application of a shader on a surface, so definitely learn to work apply them appropriately, as surfaces such as glass and liquid usually require appropriate shaders to help them look photo-realistic.

Hope this helps.

Anyone else have some input for LAD3D?

To modify the part about the textures above: Textures are not just image maps. Procedurals such as checkerboard and crumple patterns are textures, as well.
