Geometry clipmaps are a neat rendering technique for drawing huge terrains in real-time. They were first published in 2004, and a practical GPU implementation was described shortly after. Those articles don’t really explain everything you need to know. In particular there are some some unexplained things that seem to add unnecessary complexity, but are actually crucial. The main motivation for writing this blog post is I tried to simplify those things away then ran directly into the problems they resolve which was annoying and took a lot of time.
