When you scale an object, the only point of the object that won't move is the
point that rests at <0,0,0> (assuming that you're scaling all axis).
To understand what is happening, try the following scene using different values
for myScale. Note that we divide the radius of the spheres by the value of
myScale. This means that the scale size doesn't affect the radius of the
spheres, only their positions.
camera {
location <0.0, 0.0, -10.0>
look_at <0.0, 0.0, 0.0>
}
light_source {
<0, 0, 0> // light's position (translated below)
color rgb <1, 1, 1> // light's color
translate <-30, 30, -30>
}
#declare myScale = 1;
sphere{
0,0.25/myScale
scale myScale
pigment{rgb<1,0,0>}
}
sphere{
1,0.25/myScale
scale myScale
pigment{rgb<0,1,0>}
}
