hi users,
i have tried to create a simple example using fog. As I understand it the
start and end values define where the fog starts and ends relative to the
camera?
but
not matter what values I use it doesn't effect my rendering. I seem to
always get the same fog rendering.

Hi Peter,
As the osg fog is a wrapper for the (fixed functionality) OpenGL fog,
you can use the OpenGL docs for this. There you will see that the start
and end values only make sense for the linear mode, not for exp or exp2.
However, density does make sense for exp and exp2.
Regards, good
