The Terrain Editor Artifex Terra 3D is a heightmap based realtime terrain and landscape modeling and texturing application trying to combine the usability of classic 2D painting programs with 3D content generation. Offering a great variety of powerful and fine resolving tools and filters while remaining well within 2 boundaries: simplicity & practical productivity. The fast learning curve enables inspiring creation within a very short time, even for beginners. Artifex is designed very brush-centric, because we strongly believe, that the brush, even after centuries, still is the artist's most important tool. That in mind, we are of course always open for user suggestions that lead to further improvements and make terrain generation even more fun.
