Foil 20 Terrain rendering in VRML

From Study of Use of Databases for VRML and Application to GIS Research Seminar -- 9 february 1996. by Krzysztof Walczak * See also color IMAGE
Second Approach
The whole surface is divided into parts covering areas 20 x 20 points.
Each part is modeled in VRML separately. Only lighting is common in the main file.
The main file is an "index" that indicates the parts of world that should be loaded.
While moving the viewpoint above the surface the areas that are no longer necessary disappear and new areas are loaded.
The rendering resolution of the an area depends on the distance from the user viewpoint.
