Member Data Documentation
◆ color
| H3DUniquePtr< SFColor > H3D::X3DFogObject::color |
The color of the fog.
Access type: inputOutput
Default value: 1 1 1
Referenced by H3D::LocalFog::enableGraphicsState(), H3D::Fog::renderFog(), and X3DFogObject().
◆ fogType
| H3DUniquePtr< SFString > H3D::X3DFogObject::fogType |
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.
Access type: inputOutput
Default value: "LINEAR"
Valid values: "LINEAR" | "EXPONENTIAL"

◆ visibilityRange
| H3DUniquePtr< SFFloat > H3D::X3DFogObject::visibilityRange |
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. A visibilityRange of 0.0 disables the fog.

Default value: 0
