 In jMonkeyEngine 3, colors and textures are represented as Material objects.
 
 *  All Geometries must have Materials. To improve performance, reuse Materials for similar models, don't create a new Material object for every Geometry. (E.g. use one bark Material for several tree models.)
-*  Each Material is based on one of jme3's default Material Definitions (.j3md files) that are included in the engine. Advanced users can create additional custom Material Definitions (see how it's done in the <<jme3/build_from_sources#,jme3 sources>>).

 *  *Quad Tree:* The entire terrain structure is made up of TerrainPatches (these hold the actual meshes) as leaves in a quad tree (TerrainQuad). TerrainQuads are subdivided by 4 until they reach minimum size, then a TerrainPatch is created, and that is where the actual geometry mesh lives. This allows for fast culling of the terrain that you can't see.
