How to modify Perlin (not simplex) noise to create continental like terrain generation
I have been playing around for a day with Perlin noise, and I am currently stuck. Most of the modifications I have made to the algorithm produce more or less the following:
Now, this is a very good ...

Why is it twice as expensive to make a noise function that can be tiled?
I've seen in several places that making Perlin noise loop seamlessly requires calculating it twice in slightly different ways, and summing the two results.
This Perlin noise math FAQ gives a formula:
