Grome (short for Ground Moeling Environment) is a 3D simulation software for game environment that was especially designed for game developers, developed by Quad Software from Romania in 2007. However, its applications are not limited to entertainment industry. More than a terrain editor/level editor, it is also a complete scene constructor. In fact, it was also successfully used in some other cases, for example: virtual reality projects, real-time 3D simulation, the creation of scenes for offline rendering, and more.

World Creator (formerly called GeoControl) is a professional and powerful procedural terrain and landscape generating software developed by BiteTheBytes from Germany. It is mainly used to create vivid and lifelike virtual 3D environment for games, movies and artworks. With the creative tools, efficiency improvement, real-time editor, random terrain generation and so on features, World Creator makes the creation of terrains and landscapes become easier, faster and more fun.
