Terrain

In March last year I made a terrain renderer that used noise functions to generate a reasonable looking mountain range. Since then I've learned a lot and I would like to re-visit it but this time take into account:

• Normal maps
• Texturing
• Interpolation between LOD levels
• Decent lighting
• Post processing (HDR?)
• Lots of small optimisations

I would also like to give test driven design (TDD) a chance, and this seems like the perfect place to use it. I had a look at Boost.Test, being boost I trust it to be high quality. It also seems reasonably easy to use.

Here is the old terrain renderer on youtube:
