have you looked in gerrits github addons tree: http://github.com/vossg/OSGAddOnsGV I'm not sure if it's in there, but that is the location mentioned upthread. Perhaps Gerrit can chime in with more details. > Also, i tried to run testQuadTreeTerrain.cpp, but it does not work. It > gives an error of vector out of range.

Is this a bug? yes, it seems the index calculation has an off by one error if width is even (which is pretty bad if you want to use power of two sized heightmaps... ;) ). I'll take a look if I can fix it, I'm not very familiar with the code, so this mostly depends on whether this mistake is only in calcD2Value or if similar ones are all over the place.
