Re: [GD-General] Data format for terrain

Have you looked at geometry clipmaps?  Hugues Hoppe and Arul Asirvatham
have an excellent article in GPU Gems #2.  They allow for high
resolution height maps giving more control to artists.  PTC can compress
the height map to 100:1.  There is a lot of work to making geometry
clipmaps work within a game, but it's worth a look.
