A friend of mine brought a good idea, why does nehe prefer to use GLaux then GLut? What is the difference between the two? What the difference in programming if the use the one or the other? Does it make it easier for you, the programmer, or for displaying the graphics?

Glut is a full, active cross-platform open gl toolkit which is a heck of a lot better than glaux, however, NeHe's tutorials are windows API based, meaning that the complexity and features of Glut werent really needed by him at the beginning of his openGL knowledge. The only reason he uses GLAux at all is because it has a quick and dirty bitmap loader, not for any of its window creation and message abilities. the non bitmap tutorials have no use for it at all, and in the ones that do, you can very easily patch the GLaux replacement code from the front page to use the default windows bitmap loader functions instead of glaux.
