Hello all,
I have a problem with
gluLookAt(v3dEye.x, v3dEye.y, v3dEye.z, // eye position
v3dView.x, v3dView.y, v3dView.z, // look at position
0.0f, 1.0f, 0.0f); // z-up vector
I use it to set my camera and it work well.
But if I look from
top (e.g. v3dView=(0,0,0) and v3dEye(0, 1, 0)
or from bottom (e.g. v3dView=(0,0,0) and v3dEye(0, -1, 0)
the scene crashes (the screen just became black).
Is there a limitation of the function gluLookAt?
If so, how can I create a top/bottom view of the scene?
thank you very much
Wolli
