If you want to use a fixed viewing direction while moving the camera location,
you can use PovRays built-in vector arithmetic:
#declare LOCA = <53,-11,-41>;
#declare DIREC = <-42,34,42>;
camera {
location LOCA
sky -y
right -4/3*x
look_at LOCA + DIREC
angle 67.3801
}

| 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 (...) (25 years ago, 4-Sep-01, to lugnet.cad)
