How to make one-axis tileable simplex noise?
I made a program that uses perlin noise to generate a height map. It worked very good. Later I changed it to use simplex noise.
What I want to achieve now is that the left edge fits in the right ...

Zooming in on procedural generated 2D terrain? (LOD)
My question is what methods are there to "zoom in" on a procedurally generated map using Perlin Noise (or Simplex).
If I have for example this generated
and I wanted to "zoom" into that little red ...

Using Perlin/Simplex noise in a 2d tile game for terrain generation
I've been doing a bunch of research regarding procedural 2d terrain generation and have come to the conclusion that the use of perlin/simplex noise seems to be the way to go for most things.
I've ...

Are there any methods for generating rivers on-demand with Perlin/Simplex noise?
I'm aware of many methods for procedurally generating rivers, but they require an entire heightmap beforehand in order to work. For instance, they may require to find a high position on the map and ...

How do I create tileable 3D Perlin/Simplex noise?
I have a library which provides functions for 1/2/3/4-D simplex noise. With that I successfuly created a tileable 2D cloud texture (see How do you generate tileable Perlin noise?).
Now I want to ...
