void vtFog::SetFog	(	bool	bOn,
		float	start = 0,
		float	end = 10000,
		const RGBf &	color = s_white,
		osg::Fog::Mode	eType = osg::Fog::LINEAR
	)

Set the Fog state.

You can turn fog on or off. When you turn fog on, it affects all others below it in the scene graph.

Parameters:

bOn	True to turn fog on, false to turn it off.
start	The distance from the camera at which fog starts, in meters.
end	The distance from the camera at which fog end, in meters. This is the point at which it becomes totally opaque.
color	The color of the fog. All geometry will be faded toward this color.
eType	Can be FM_LINEAR, FM_EXP, or FM_EXP2 for linear or exponential increase of the fog density.
