Detailed Description

This class provides a simplistic example of how to add a terrain-rendering implementation to the vtlib library. It contains the bare skeleton of terrain rendering code, taking an elevation grid as input and doing a naive, brute-force rendering all the geometry via OpenGL each frame.

To add, or wrap, your own terrain rendering algorithm, simply make a copy of BruteTerrain and rename it, then fill in the methods with your own functionality.

The documentation for this class was generated from the following files:
