Haha thanks, its just some sphere-mapping and simplex noise, not hard to do really.
Takes alot of trys to create something just right, thats why i made this simple animation app.
The game where im going to use the algorithms is 3d and will be optimized (need to write some engine to zoom into planets / stars without rendering the rest of the globe).
I could position the glow and stuff right, but why waste processing power with extra transformations and depth testing, the app will stay 2D since its just for testing the algorithms.
The globe is drawn using GLUT with a simple 400x400x400 sphere.
So anything under -200 / 200 will be cut of like this image (-100 / 100):
