Are you sure? Keep in mind, VIEW is in camera space, not in world space.

I guess either way it needs to be updated. Because it is a normalized direction, rather than a vector from one point to another.

[Arnklit]

Yeah it's definitely a normalized value. I'm pretty sure it's from fragment to camera.
I needed to make a normal point at the camera, so looking at the documentation I assumed I would have to do:

NORMAL = -VIEW;

But that will look like the normal is pointed away from the camera.

NORMAL = VIEW;

Looks like the normal is pointed towards the camera.

Thanks for the explanatory image. It's very helpful for me to put my head back on straight. Yes the view vector is relative to the fragment.

It is the direction to the camera from the current fragment. It is used in conjunction with light direction and surface normal to compute lighting.
