I still don't understand. I don't see any difficulty in controlling the
roll of the camera. I roll it just like any other object.
Or do you mean that you have to use rotate _after_ location and look_at
and after that making the camera to look at a certain point is difficult?
Well, you can use something as simple as this:
#declare CamTiltAngle=radians(30);
camera
{ sky <sin(CamTiltAngle),cos(CamTiltAngle),0>
location <1,2,-4>
look_at 0
}
