Hi Alex, sorry I did not see your original post. As Justin says I make available an open source terrain translator/generator in java. I am still at the stage of developing it into a general framework - getting the interfaces and design patterns sorted out - there will be an update this weekend (which I reccomend you wait for). There are example implementations for generating VRML and other output (including java3d) in multirezolution trees with the distribution. Its java3D output implementation is a very crude first step. So there are currently no LODs built-in : it simply generates java source code for a height grid in triStrips. .I'm afraid and :I havenot had the time to do any real work on it. However, if it is the sort of thing you are after I will be happy to go further with it.
