Terrain Bender applies progressive bending to digital terrain models for 3D mapping. It offers interactive tools to add a bent base to a digital terrain model.

Terrain Bender offers specialized tools for the bending of the terrain models :

• progressive bending
• curved horizon bending
• vertical exaggeration adjustable in foreground and background
• preview with perspective camera, parallel camera, and 360° cylindrical panoramas
• illumination settings
• hypsometric tinting, haze simulation, and texturing
• import and export of terrain models in ESRI ASCII grid file format

Terrain Bender provided interactive features 3D maps, but the final yield is best done with the ray tracing software.

Terrain Bender is free and open-source software. Version 1.0.6 of 4 February 2010 is available for Windows, Mac OS X and Linux. Please see the system requirements, and download an example terrain model.
