PCG, A Family of Better Random Number Generators

Wow talk about a coincidence - I just implemented this algorithm today as the RNG for some bootstrapped statistic code. One thing I can say is it very fast, but the code for seeding is not great on any platform without /dev/random.

I implemented the mersenne twister to generate 2d planets in a galaxy of a game I am working on a while ago.. I didn't know about this pcg and it's an interesting read!

I had been limited in selection on the random number generator reproducibility (so that each planet is only stored as the seed for the generator)

I'll have a try later on, it'd be interesting how a sampling of planets turn out from both rngs, if they are visually different - the rng is used both for features and for the perlin noise that generates cloud&land textures, so any artifact should come up easy in the textures

Give it a try - I just used the minimum C code function and implemented my own seeding function.
