Detailed Description
A material in the scene graph.
A material represents information about a single surface type in the 3D scene graph, including texture, colour, lighting, tiling, and so on; most of the materials in FlightGear are defined in the $FG_ROOT/materials.xml file, and can be changed at runtime.
