 For editing the vegetation system to areas can be used in the World Editor. The first one is in the properties area and allows to add, remove and reorder vegetation layers as well as editing their variations. For editing the rule base the node editor is used which can be found in the same area as the 3D view ( click on the Vegetation button on top ). This editor works like most other node based editors and people familiar with those should be immediately familiar with this one. For those new to this kind of editing a small introduction is given. For editing the vegetation system to areas can be used in the World Editor.

 ====== Geometry Rule ====== ====== Geometry Rule ======
-The geometry rule is an Input rule and provides informations about the instance the rules are currently evaluated upon. The height output slot contains the absolute y coordinate of the position of the instance in the world and is a value type slot. The normal output slot contains the normal of the ground the instance is sitting upon and is a vector type slot.\\+The geometry rule is an Input rule and provides informations about the instance the rules are currently evaluated upon. The height output slot contains the absolute y coordinate of the position of the instance in the world and is a value type slot. The normal output slot contains the normal of the ground the instance is sitting upon and is a vector type slot. The terrain type slot returns the type number of the height terrain texture the most dominant or with other words the terrain texture the instance sits upon. This terrain type number can be used to limit plants to grow only on patches of terrain with a given texture. The type number can be chosen freely by the mapper and is not required to be unique for each texture. Usually this number is linked to a math rule with an equal operator. This test works since the equal test is within a small epsilon around the number. Otherwise two math rules with less than and greater than operator can be used. Later solution is useful if the type numbers are laid out in such a way that entire ranges can be checked instead of a single number. The terrain type slot is a value type slot.\\

 The vector-math rule is a Processing rule applying a mathematical operation to one or two input vectors. This rule behaves similar to the math rule but operates on vectors. One difference is that some vector operations produce a value instead of a vector. Therefore this rule has two output slots. Depending on which operation is selected one of the two slots returns the result while the other returns a default 0 value or 0 vector. Make sure to pick the right output slot.\\ The vector-math rule is a Processing rule applying a mathematical operation to one or two input vectors.
