Terragen is a scenery generator, created with the goal of generating photorealistic landscape images and animations. It is available for Windows and the Mac OS. At this stage in its development, Terragen is free for personal, noncommercial use.
Although Terragen is a continually evolving work-in-progress, it is already capable of near-photorealistic results for professional landscape visualisation, special effects, art and recreation. Terragen has been used in a variety of commercial applications including film, television and music videos, games and multimedia, books, magazines and print advertisements.
Despite the fact that Terragen can be used for professional landscape visualisation projects, it is accessible and easy to get started with. You could be rendering your first landscape image in as little as 15 minutes after installation.
You can view a gallery of images created by Terragen users here.
Terragen has a native user interface, using facilities provided by the operating system of the respective platform, as opposed to the custom user interfaces used by many similar applications. This means Terragen can follow the usage conventions of each platform as closely as possible, which ensures that it looks and feels just like the other applications you use and means there is no learning curve with respect to the basic operation of Terragen.
