I am trying to mess around with the terrains i found this page https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:advanced:terrain. I am tring to get that code going but dont know what to import for TerrainQuad, AbstractHeightMap, and TerrainLodControl. These pages about how todo things are great but am i missing somthing because not one of them seems to tell me what to import.
What version of jme3 do you use?
Try to use the nightly build if some classes does not exists in your version
