Desiring jagged results from simplex noise or another algorithm just as fast

I'm wanting to do some placement of objects like trees and the like based on noise for the terrain of a game/tech demo. I've used value noise previously and I believe I understand perlin noise well enough. Simplex noise, however, escapes me quite…

Map Generator with Weighted Perlin Noises

I have got an arbitary number of perlin noise maps and a weight for each. The sum of all weights is 1, but that shouln't make a difference. I want to get that noise with the highest value regarding the weight. My first approach was to get the…
