> Hi, After watching that video: [Coding Adventure: Hydraulic Erosion - YouTube](https://www.youtube.com/watch?v=eaXk97ujbPQ) And reading that paper: [https://www.firespark.de/resources/downloads/implementation%20of%20a%20methode%20for%20hydraulic%20erosion.pdf](https://www.firespark.de/resources/downloads/implementation%20of%20a%20methode%20for%20hydraulic%20erosion.pdf) I decided to take a go at generated terrain using hydraulic erosion. The code below definitively gives some results although they are not completely as expected. Here some before/after pictures: To play with the code, just hit play, zoom a bit with the middle mouse button…
