Hi Folks!
I have problems using the upvector-parameters of gluLookAt(…).
I have my camera positioned at the center (0,0,0) and it should face an object (x,y,z).
The Objects position always changes, so do I have to change my upvector too, because it´s the normal-vector to the vector between my oject and cameraposition (???)…
How is it meant?? Anybody please…
Thanks in advance!
