perlin-noise

I've been learning about Procedurally Generated Content lately (in particular, Perlin noise). Perlin noise works great for making things like landscapes, height maps, and stuff like that. But now I am trying to generate structures more like mountain ranges (in 2D, as 3D would be way over my head right now) or underground veins of ores.

I can't manage to manipulate Perlin Noise to do this. Making a cut off point (i.e. using only the tops of the 'mountains' of a heightmap) wouldn't work, because I would get lumps of mountains/veins. Any suggestions?

Thanks,
Numeri

Procedural Generation of tile-based 2d World

I am writing a 2d game that uses tile-based top-down graphics to build the world (i.e. the ground plane). Manually made this works fine. Now I want to generate the ground plane procedurally at run time. In other words: I want to place the tiles (their textures) randomised on the fly. Of course I… >>> More

Difference Procedural Generation and Random Generation

I am very new to game development but I was able to scour the internet to figure out Perlin noise enough to implement a very simple 2D tile infinite procedural world.

Simplex noise vs Perlin noise

I would like to know why Perlin noise is still so popular today after Simplex came out. Simplex noise was made by Ken Perlin himself and it was suppose to take over his old algorithm which was slow for higher dimensions and with better quality (no visible artifacts). Simplex noise came out in 2001… >>> More
