They are acctually the same thing. gluLookAt(); just does it for you. I personaly disagree with NeHe teaching the use of the camera by using translate and rotate, but he is a much better coder than me, so i wont argue. I would use gluLookAt in your case. If u need help using it, just post

It means "USE" "gluLookAt(xpos,ypos,zpos,xview,yview,zview,xvector,yvector,zvector);"
its easier if u ask me. But its best just to search "camera" in the search forum thing, and u will find loads of stuff.

gluLookAt is fine for beginner''s ogl.
However, once you''re passed that point, and have a solid engine: Use your own Matrix44 class, and load it into openGL with glLoadMatrix.

so what''s so bad about LookAt ? It''s easy to use and does exactly what you think it does..
Why is using your own 4x4 matrix better ?

Becouse you''ll need that matrix for bunch of other things later on.
You should never let your fears become the boundaries of your dreams.
