Generating erosioned-perlin-based procedural worlds with leaflet and web workers
I woked with leaflet-perlin () to include erosion and rivers. This is what I got, I hope you like it.
It is inspired by leaflet-fractal (github.com/aparshin/leaflet-fractal), uses code from http://www.ecse.rpi.edu/Homepages/wrf/Research/Short_Notes/pnpoly.html for identifying points inside a simple polygon, and perlin noise is taken from Stefan Gustavson.
The grid is based in random quadrilaterals for future convenience. For the interpolation, I map the quadrilateral to a unit square and use a bilinear interpolation. (I also coded a weighted interpolation for the first tries, I kept the lines there in case.)
Do whatever you want with it, enjoy!
