LocalFog
LocalFog simulates atmospheric effects by blending distant objects with fog color. LocalFog effects occur around the local transformation center, rather than bound to the viewer. The nearest LocalFog node within range takes precedence over other LocalFog and Fog nodes.
The LocalFog node belongs to the EnvironmentalEffects component and its container field is children. It is available since X3D version 3.0 or later.
Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFBool [in, out] enabled TRUE
Enables/disables node operation.
SFString [in, out] fogType "LINEAR" ["LINEAR"|"EXPONENTIAL"]
Specifies algorithm for rate of increasing Fog, either LINEAR or EXPONENTIAL.
Hint
EXPONENTIAL is more natural but also more computationally expensive.
Warning
Do not wrap extra quotation marks around these SFString enumeration values, since "quotation" "marks" are only used for MFString values.
SFColor [in, out] color 1 1 1 [0,1]
Fog color.
Hint
Match Background color to make objects fade away.
See Also
SFFloat [in, out] visibilityRange [0,-∞)
Distance in meters where objects are totally obscured by the fog, using local coordinate system.
Hint
VisibilityRange 0 disables Fog.
