Example

From the MIT POVray tutorial

#include "colors.inc"
background { color Cyan }
camera {
    location <0, 2, -3>
    look_at  <0, 1,  2>
}
sphere {
    <0, 1, 2>, 2
    texture {
        pigment { color Yellow }
    }
}
light_source { <2, 4, -3> color White}

POV-Ray can accomplish wildly photorealistic rendering via raycasting.
