jMonkeyEngine is a 3-D game engine for adventurous Java developers

There is a newer version: 3.7.0-stable

MaterialDef Terrain {

        // Parameters to material:
        // regionXColorMap: X = 1..4 the texture that should be applied to state X
        // regionX: a Vector3f containing the following information:
        //      regionX.x: the start height of the region
        //      regionX.y: the end height of the region
        //      regionX.z: the texture scale for the region
        //  it might not be the most elegant way for storing these 3 values, but it packs the data nicely :)
        // slopeColorMap: the texture to be used for cliffs, and steep mountain sites
        // slopeTileFactor: the texture scale for slopes
        // terrainSize: the total size of the terrain (used for scaling the texture)
