Step-by-step 3D terrain generation course!

''UPDATE 2/20/2006: After about a month, the project is now finished. You can go through the series and read my explanations for each step, or you can just page through and gander at the pretty pictures.
I’m programming in C++ and using OpenGL for the rendering.
A common approach is to keep the elevation data as a big greyscale image. This makes it easy to edit, and easy to “see” what the land looks like outside of the program. I’ll use a bitmap (windows BMP files are a good choice since they are easy to load, easy to create, and have lossless compression) where each pixel represents a single point on our grid. The brighter the pixel, the higher the point.
