Grid Generation and Geometry Description

Here are some examples for the possibilities to use IBG.

More information about the IBG package is available via anonymous ftp.


Example: Rügen Island (Germany):
Rügen
This grid was created in the following way:
The geometry description also allows to describe complex 3D geometries containing intersections without explicite specification of the intersection lines. So, the grid
Rohr
was created using the program ibgmain3line.c
Segments with nontrivial topology also can be simply created. The grid
Hole
was created using the program ibgmainhole.c
Using elevation data obtained from the 1-degree USGS Digital Elevation Models we have created the following elevation profile:

Great Falls East:
falls-profile
Grand Canyon East:
canyon-profile

An YDL output possibility allows to use the SGI powerflip program for visualization:

Great Falls East:
falls-powerflip
Grand Canyon East:
canyon-powerflip canyon-powerflip2
