TGEN - Terrain Generator
The rules in the terrain generation system are also referred to as affectors,and are organized into layers. Boundaries refer to terrain designer- or artist-defined regions of virtual terrain for which the desired rules have effect. Filters refer to conditions to be considered when applying affectors. Layers can be arranged in a hierarchy with a parent-child or tree-leaf relationship. Examples of boundaries include circles, rectangles, and polygons. Examples of filters include filtering by slope, height, shader, direction and fractal. Examples of affectors include those that affect height, color, shader, flora, and radial flora. Boundaries, filters and layers are described in greater detail below. The terrain generation system also includes families, which refer to groups of assets such as textures, geometry or even algorithms. Families can include children with weights. This could involve choosing an asset by selecting a one weighted child. For example, this could allow the users to choose a "grass" family for a region, but when the terrain system generates the grass family, it can choose one of the children of the grass family, which results in the rendering of a single grass shader. Examples of families include shader families, blend families, flora families, radial flora families, and fractal families. Shader families refer to grouping shaders for placing textures. Blend families refer to grouping shaders for selecting alpha blend masks. Flora families refer to grouping geometry for selecting flora. Radial flora families refer to grouping shaders for placing radial flora. Fractal families refer to grouping fractals for reuse within different rules.

LYRS - Layers
Layers & Affectors
Basically the role of layers is to affect the data contained in the different families. They can contain any number of other sub-layers. Their order is important.
A layer deals with the families trough Affectors. There are different types of them, each one has it's own role. Can have Affector for texturing, flora, areas...
Boundaries, filters, and affectors can be defined in layers and sublayers, such that a single location in the terrain can have multiple terrain rules. A layer without boundaries (or filters) is "unbounded," and can affect as much as the entire landscape. A layer with a boundary allows the affectors in the layer and sublayers to be applied to the region specified by the boundary.

Description
Using the example rules listed above, the corresponding rule description can perform the following: 1. Set the height of the terrain everywhere to 10 meters(1a) and assign the rock shader(1b). 2. Then, in a 500 meter circle(2a) originating from coordinates (500, 500), gradually decrease the height from 10 meters to 0 meters(2b), place the mud shader(2c), and create a black band where the height of the terrain at a given sample point is between 13 and 17 meters.(2d, 2di, 2dii) 3. Finally, in a rectangle(3a) from coordinates (-500, -500) to (500, 500), place conifer trees(3b) and dead grass(3c) within the rectangle.
