I've been toying with procedural generation a lot recently but this is the first time I've come up with my own algorithm from scratch.
I'm very pleased with the results.

Your islands look very nice. I think it would also look very cool in 3D. Assuming your code generates a heightmap and you know how to use the matrix mesh library, you just pop in some generic transparent plane for the surface of the water and you're all set. There could also be a clone of the matrix with a repeating grain/static texture to give it detail up close.

That's a good point, yes the map(x,y) array stores a "height" value (currently 0 to 255). I see two issues though: matrices can only be about 70x70 resolution, and texturing would be difficult.

@OBese87-

Luckily for you, there is an exact library that I had in mind. It allows you to use blanket textures and heightmaps of any resolution.

I've redone the colouring and it looks much better. It's all trial and error though, I wish I knew a proper formula for getting nice colours.

Now to try with those matrices...

I thought I posted on here before... hmm...

OBese87 - can you export a 2048x2048 texture? [or 4096x4096 even]

EDIT

Realised why I gave posting a miss... this is for DBC which I have but used for 5 minutes or so...

Made a few tweaks to the code and colours. Added a gradient function to get smoother colour transitions.

OBese87 - Hmm, 3DWS is giving me issues with loading height maps... I will try converting that sample and see if I can create anything with it... just to show how it looks in other applications, such as 3WS

Very cool, it indeed looks like an island. And the code seems relatively simple. (works in DBP btw)

Thanks! Yeah I was surprised when it worked fine in DBP, that is rare for my DBC code.

verry nice coding!

can you make it to a matrix and post your code here too?

that would be nice, i am not so good with the matrix programming.

greetings!
