Mountain 3D is a virtual landscape generator software. It is based on fractal technology, and will create the relief, the forests, the ground, the rivers, and the sky with clouds. After creation, landscapes can be modified by a ground editor part of the the software. You can imagine a landscape and Mountain 3D will create it. It can also read DEM files for real ground elevation files. Mountain 3D allows to import and display the true colours from a real landscape from an aerial photography. The result is a picture file in BMP or JPEG format, or a movie file in AVI or MPEG format.
