Ok, I've saved the first POV file that was generated. Here is the camera
section of the code; I had specified a minimum distance of 75000:
// Camera (Latitude,Longitude,Radius = 0,0,0)
camera {
#declare PCT = 0; // Percentage further away
#declare STEREO = 0; // Normal view
//#declare STEREO = degrees(atan2(1,12))/2; // Left view
//#declare STEREO = -degrees(atan2(1,12))/2; // Right view
location vaxis_rotate(<0,2.55207,-51858.9> + PCT/100.0*<0,0,-51858.9>,
<0,-2.68935e+009,0>,STEREO)
sky -y
right -4/3*x
look_at <0,2.55207,0> // calculated
angle 1
rotate <0,1e-5,0> // Prevent gap between adjecent quads
//orthographic
}
Unfortunately, nothing jumps out at me as being related to the minumum distance,
but that may just be my ignorance of the POV syntax.
For now, I'll keep going with trial and error to get the distance right. Of
course, if you have any other suggestions, I'd be glad to hear them.

| (...) I would have thought that the <0,2.55207,-51858.9> was the camera distance, but taking the square root of the squares of these numbers is less than 75000, so I would have expected it to be 75000. Are you using mega-pov? Someone reported that (...) (21 years ago, 7-Oct-03, to lugnet.cad)
