Terrain and procedural rivers
I have managed to get a nice random/procedural terrain generator plus lakes working based off of Perlin noise and seeds, but I wish to create rivers in flat bits of land. I have had a look around and can't find anything relevant?
Any ideas how I can achieve this?
By rivers I mean something like this: http://www.shamusyoung.com/twentysidedtale/?p=12076
I was thinking I might have to go over the terrain again with noise or something?
I'm not much of an expert but here's my opinion.
If you created the terrain via "Create"-GameObjects"-"Others"-"Terrain" then you can just add texture in similar to texturing terrain but only with a bit of particles..
The question is about creating rivers and lakes procedurally, not by manually painting. Converting answer to comment.
Hi, you could create procedural terrain there are few free tools that do that.But before proceeding Can i ask something.Is the procedural terrain created at runtime (when the player is playing or when the levels loading).Either way it would quite some time for the computing process to take place

When you generate the terrain with perlin noise, you get set some kind of number which presents the "sealevel" height on the Y-axis. Once you're done generating, you can add set the with of the standard water prefab to the size of the map. (renderer.bounds.size). The mountains or peaks which have a higher Y-axis value than the sealevel, are land, the one below are sea. Heres a picture of the side view

This is something I'm researching and I've found a paper that investigates procedural river generation from river networks, to meandering techniques and the creation of river deltas...
Sections 5,6 and 7 may be of particular interest to you...
