A simple question. It seems that there always is a default point light source which is located in the eye, we assume it is light nr 0. The problem is that if we write "glDisable(GL_LIGHT0)", or any other light source for that matter, it's still there! We cannot turn off light sources that way, only by disabling lighting completely with "glDisable(GL_LIGHTING)". Anyone who recognizes the problem?

Hehe, well, about the light source that's located at the camera position, that's definitely true, but that thing about not being able to turn off the light sources, that was just because we were doing it inside of a "glBegin()...glEnd()" :-) Not so strange after all.

I don't exactly in what cases the light source defaulting in the eye position occurs, but it does sometimes, and one of those times is when you have not specified any lightsources, but turned on lighting. Then the default light source is a point light source being placed in the eyeposition.

Thanks anyway!

According to the Red Book, the default light position is (0, 0, 1, 0). In other words, a directional light that points along the negative z-axis.
