Hi
I need to move a camera. I defined my projection ortho
glOrtho(-200, 200, -200, 200, -20, 200);
and a like to move a camera position at
gluLookAt(0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, -20, 200);
but its statement doesn’t make anything.
The case is that I need to know the observer’s vector dir and make some calculations.
Where is my error?
