Oh, yeah, I use version 3.1a for windows.

It seems in fact that the bug is much more perverse...

#declare EarthMoonDistance =    469928448; // Earth-Moon distance
#declare EarthRadius       =      6379439.6; // in meters (thus, 1 pov unit =~=
1 m)
#declare MoonRadius        =      3476183; // for now

box
 {
  0, MoonRadius
  translate <0,-EarthRadius,0> + EarthMoonDistance*vnormalize(<0,0.5,1>)

  pigment { Green }
 }

Yields a visible box, but:

sphere
 {
  0, MoonRadius
  translate <0,-EarthRadius,0> + EarthMoonDistance*vnormalize(<0,0.5,1>)

  pigment { Green }
 }


does not yield a visible sphere... the object doesn't even exist!

suggestions?



Best,

    S.
