.SH "Detailed Description"
.PP 
The \fBSoVRMLFog\fP class is used to specify a global scene fog\&. 

\fBThe detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997)\&. It is copyright The Web3D Consortium, and is used by permission of the Consortium:\fP
.br

.br
 
.PP
.nf
Fog {
  exposedField SFColor  color            1 1 1      # [0,1]
  exposedField SFString fogType          'LINEAR'
  exposedField SFFloat  visibilityRange  0          # [0,inf)
  eventIn      SFBool   set_bind
  eventOut     SFBool   isBound
}

.fi
.PP

.PP
The Fog node provides a way to simulate atmospheric effects by blending objects with the colour specified by the color field based on the distances of the various objects from the viewer\&. The distances are calculated in the coordinate space of the Fog node\&. The visibilityRange specifies the distance in metres (in the local coordinate system) at which objects are totally obscured by the fog\&. Objects located outside the visibilityRange from the viewer are drawn with a constant colour of color\&. Objects very close to the viewer are blended very little with the fog color\&. 
.br

.PP
A visibilityRange of 0\&.0 disables the Fog node\&. The visibilityRange is affected by the scaling transformations of the Fog node's parents; translations and rotations have no affect on visibilityRange\&. Values of the visibilityRange field shall be in the range [0, )\&. 
.br

.PP
Since Fog nodes are bindable children nodes (see 4\&.6\&.10, Bindable children nodes http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.10), a Fog node stack exists, in which the top- most Fog node on the stack is currently active\&. To push a Fog node onto the top of the stack, a TRUE value is sent to the set_bind eventIn\&. Once active, the Fog node is bound to the browser view\&. A FALSE value sent to set_bind, pops the Fog node from the stack and unbinds it from the browser viewer\&. More details on the Fog node stack can be found in 4\&.6\&.10, Bindable children nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.10)\&.

.PP
The fogType field controls how much of the fog colour is blended with the object as a function of distance\&. If fogType is 'LINEAR', the amount of blending is a linear function of the distance, resulting in a depth cueing effect\&. If fogType is 'EXPONENTIAL,' an exponential increase in blending is used, resulting in a more natural fog appearance\&. The effect of fog on lighting calculations is described in 4\&.14, Lighting model (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.14)\&.
