Waterbased Street Growth

This modules offers multiple ways to generate a street network on top of a terrain in consideration of the rainwater rundown direction. The code accessible through the DeCodingSpaces python components and is based on Procedural Cities. While the linked project uses perlin noise as a base grayscale layer, this algorithm is deterministic through the use of a bitmap like grayscale layer. In the example the heightmap of the terrain informs this layer and therefore streets follow its slope/rainwater rundown direction.
