GEMM is a plugin for MapMagic, an extremely powerful library for node-based procedural terrain generation. GEMM adds various generators to MapMagic in order to expand its power, and to dramatically simplify various usage scenarios.

At present, GEMM contains the following generators: (read the docs though)
- Mux, Demux, Breaker: Allowing you to "multiplex" multiple data streams you wish to process through the same nodes;
- Slice: Partition masks with arbitrary precision;
- Stratify: Separating objects into different groups according to multiple masks;
- Once, Scatter Once, Several: When you need absolute control over the exact number of objects you want to spawn and/or where they have to be;
- Randomise Input/Output: Permitting the creation of "branching" graphs controlled by a random seed;
- Varying Objects/Trees: What's better than populating a forest or scattering objects using just one prefab? Doing it with a lot of prefabs.
- Scaling Voronoi: Like regular voronoi, except you decide how large the "patches" are;
- Label: To write notes on, for those cases where your graph is too large to keep solely in your head. It's useful, honest!

Naturally, even more generators will be added later in time. And since making generators is fun, if you have any interesting ideas, you should let me know what they are in the forum thread or over emails. :)
