     30 * \brief This class provides a management interface to control terrain modification.
     31 *
     32 * It is possible to modify preprocessed VirtualPLanetBuilder (VPB) Databases on the fly.
     33 * The modification can be performed in two ways:
     34 * a) Modifying only the tile data and using the standard geometryTechnique to mesh the drawable.
     35 * b) Using an userdefined geometryTechnique to create other meshes than the regular triangle mesh.
     36 *
     37 * Currently the changes are made on run time but in the pseudo loader. This way the modification does not affect the frame rate but only the delay in the tile delivery to the rendering thread.
