Thank you for replying.
I would probably enter the slope/angle information into POVray code that
resembles something more like this:
camera
{
location <1.250000, 6.986278, 4.250000>
direction <-0.28939780593, -0.00816663355, -0.95717394352>
up <0.08487440867, 0.99580411355, -0.03415767338>
right <-0.96375234144, 0.09211064543, 0.29060086839>
angle 50.000
}
This orientation would remain constant if a camera were moving (I.E. a
camera mounted to the dashboard of an automobile, or, reversely, the
headlights on an automobile. If you used camera_lookat, then the camera
would remain fixed to the object it is looking at, while it would be, in
actuality, rotating within its location in a moving object.
Keeping the angle constant while keeping the "lookat" variable would ensure
that the camera (or light) would remain fixed relative to the moving object
it is mounted to.
Hope that helps.
Mike
