When using CSG it is often useful to invert an object so that it will be
inside-out. The appearance of the object is not changed, just the way that
POV-Ray perceives it. When the inverse keyword is used the
inside of the shape is flipped to become the outside and vice
versa. For example:
object { MyObject inverse }
The inside/outside distinction is also important when attaching
interior to an object especially if
media is also used. Atmospheric media
and fog also do not work as expected if your camera is inside an object.
Using inverse is useful to correct that problem.
