Adding fog with FogFilter

The fog filter allows you to create the illusion of objects disappearing gradually in a fog when the distance between the objects and the camera increases. This is a common effect in 3D games, preventing objects from suddenly disappearing behind the far plane, usually somewhere on the horizon. The filter generates a number of viewport layers with alpha transparency distributed over a region that you specify. The transparency of the layers is based on the number of layers you define.

Instantiating the filter is easy:

renderer.filter = new FogFilter(new FogMaterial(0xFFFFFF), 16,800,2000);

It takes the following parameters:

	Parameter	Data type	Default value	Description
1	material	FogMaterial	—	The fog material. The FogMaterial class only takes one parameter, which is a hexadecimal color value.
2	segments	uint	8	Sets the number of layers. The higher this value, the lower the alpha value of the layers will be...
