> This paper describes a method for blending detail textures over terrain.
> Instead of using masks to define how much of each texture to blend into a
> given fragment of the terrain the color of the base texture is used. A color
> is assigned to each detail map used, for example some shade of green for
> grass, a shade of brown for soil, gray for rock and so on. Then, when
> rendering the terrain, at each output fragment each detail map is blended
> with a contribution inversely proportional to the ‘distance’ of the base
> texture color from the color assigned to the detail map in question. The
> blending can thus be defined 'intuitively' and per pixel so that the
> sharpness and definition as well as the diversity of the blend is not bound
> by the resolution of the base map. This is in addition to the fact that only
> one map is used for all detail textures instead of using one mask map _per_
> detail texture.
