Abstract:


    On OpenGL systems without the “clipmap” extension, a tiled approach can be used to provide the correct resolution image data for different parts of a 3D visualization, where very large texturemaps are desired. The application, called “EarthView” is a planetary browser, which can be used to view arbitrary amounts of geo-referenced image and terrain elevation data.
