15.1 - 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 MAK GDB, 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, uses the terrain library to perform terrain intersection tests for modeling ground vehicle movement, and line of sight in its sensor model.
