Introduction to the Terrain API

The VR-Forces Terrain Library is a set of classes that enable applications to read, write and query terrain databases.

Using the terrain library you can:

• Load terrain databases in formats such as OsgEarth, CDB, OpenFlight, ESRI Shapefile, DTED and CTDB.
• Perform intersection tests with the terrain geometry and vector network
• Query the vector network for information about feature data.

A simulation engine, such as VR-Forces, will use the terrain library to perform terrain intersection tests for modeling ground vehicle movement, line of sight in its sensor model for example.
