Hi o/ I'm just looking for some articles, helpful websites etc that would help me learn how to properly change a terrains level of detail the closer you get to it. The general idea is I'm planning to make a game where you can fly around a planet (high altitude, small number of vertices, less detail), the closer you get the more detail appears. Procedural textures and normal maps generated by the pixel shader and procedural geometry generated by the vertex shader. I understand the principles of perlin noise, but this is something I haven't managed to get to grips with yet. Anyway, I was hoping some kind souls could link me to some resources, or state some buzz words for me so I can start my research. Thanks :) Knossos.

Thank you for the ideas :)

Thats a huge website, I got a lot of reading to do!

Yeah, I've seen that before. Absolutely stunning work hes done.
