Public Member Functions inherited from NodeExtension
void	SetEnabled (bool bOn)
bool	GetEnabled () const
void	SetCastShadow (bool b)
	Set this node to cast a shadow, if it is under a vtShadow node. Default is false.
bool	GetCastShadow ()
	Get whether this node casts a shadow.
void	GetBoundSphere (FSphere &sphere, bool bGlobal=false)
	Get the Bounding Sphere of the node.

Detailed Description

A Fog node allows you to apply a fog to all its child nodes.

Member Function Documentation

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.
