GluLookAt

the GluLookAt function performs the same set of transformations to the world as you would have done with the glTranslate/glRotatef commands. The position is the X, Y, and Z coordinates of the Camera''s position in the world. The View is the (Position+ViewingDirection) vector (it is the direction you are looking in from the camera''s position).

The Up vector specifies your orientation in the world. The OpenGL standard is to have the Y axis as the Up vector (that''s called a right handed coordinate system). The quake games use the Z axis as the up vector. I personally prefer the former, but technically you can have any vector as the up vector (although it will distort your world if you don''t use the proper orientation that was in mind when the world was being constructed).

Hope that answers your questions.

Ah, thanks! I thought it might be something like that, but I wasn''t sure.
