ObjectTerrainGlobal Class
| Inherits: | Object |
This class is used to create a global terrain object representing a certain fragment of Earth's surface on the basis of available GIS data (elevation and imagery). The global terrain is rendered using pre-generated tilesets which represent LODs for different data layers (heights, albedo and normals).
