File loaders are built over the top of the basic parsing framework defined in the {@link org.j3d.loaders.dem} package to handle the parsing.
Since a DEM model is static geometry, there are no runtime abilities created, regardless of the flag settings.
DEM models do not contain layers, nor any other form of interesting geometry beyond the raw terrain itself.
