I have a question about terrain rendering. How do you do it :-)? I mean, what are the best ways to store the terrain data, and then convert it into 3D data to pass to the renderer (OGL, D3D, Software, etc...)? Can anyone point me to some good tutorials? Thanks.

This is a very large topic. I''ll give some links to papers that you may want to read.
