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.

Terrain generator (form name : TGEN) There are 6 different sections.

- The Shader family          (SGRP)
- The Flora family           (FRGP)
- The Radial Flora family    (RGRP)
- The Environment family     (EGRP)
- The Fractal family         (MGRP)
- The Layers family          (LYRS)

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.

Affectors

Note: Every Affector has an IHDR child wich is holding the user-custom name of the affector (here AffectorFloraCollidableConstant).

The 4 bytes Before the name is a Bool wich enable/disable the affector.

The affector-specific data is conatined After the IHDR in the last DATA form, it always starts with a byte counter.

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.
