Demeter is a cross-platform C++ library that renders 3D terrains using OpenGL. Demeter is designed for fast performance and good visual quality and makes use of advanced techniques such as dynamic tessellation (adaptive mesh) to render vast landscapes in real-time, without the need for high-end hardware. It is written as a stand-alone component that can be easily integrated into any kind of application, such as:

• Games
• Simulations
• Civil Engineering
• Construction Visualization
• Petroleum/Mineral Exploration
• Any application that needs to show 3D terrains to the user

Demeter is open source. It is available under the terms of the Lesser GNU General Public License, which are incredibly reasonable terms. Basically, you may freely download and use Demeter in your own projects, even commercial projects, without having to pay any kind of royalties or fees whatsoever. Please read the entire license document before using Demeter.

Thanks to Great Open Source Authors

Demeter is made possible through the use of these other fine open source libraries:

• SDL (led by Sam Lantiga)
• OpenSceneGraph (led by Robert Osfield)
• GDAL (led by Frank Warmerdam)
• Mesa3D (led by Brian Paul)
• SDL Console (by Garrett Banuk)

Thanks to these great people who help us all build something greater than we could build in isolation!
