Question Procedural Floating Island Generation

Does anybody have any ideas about how I could create procedurally generating floating islands like how its been done in this video?

 

Or even the method he's using to procedurally generate terrain would be helpful as of now.

 

In the video doesn't he already explain how he generates the floating islands?

Anyway, here is a basic example of procedural mesh generation:

If you make big grid of quads then you can apply a heightmap by modulating the y value of each vertex according to the corresponding height map value

 

In code you would produce what he shows you he does in Blender3D.

Replicating the complexity of all that he does in Blender is a MASSIVE undertaking.

If you wanna dabble in 3D procedural generation, start small and simple.

Look towards making floating islands that look like squat flat cylinders first.

Then iterate towards success by refining that step by step.

You're welcome to start with my UV Cylinder creation code, part of my MakeGeo project:

Thanks, I'll look into it some more.
