Optional name of the object (doesn't need to be unique). Default is an empty string.
Fog color. Example: If set to black, far away objects will be rendered black.
Defines how fast the fog will grow dense.
Default is 0.00025.
Returns a new FogExp2 instance with the same parameters as this one.
Return FogExp2 data in JSON format.
