As a visualization company that makes heavy use of Open Source software, we've developed a LandXML terrain surface importer for Blender 2.6. This video was made to show the Blender developers and community, but I hope it will inspire others to investigate the use of Open Source software for visualization.

Showing off some of the testing scenes created with our LandXML terrain import plugin. Developed for Blender 2.6 and later, the plugin reads standard LandXML terrain surface formats and supports:

- Reporting of LandXML surface data statistics
- Creation of triangulated network mesh
- Optional major & minor contours at user-defined spacing
- Contour smoothing and thickening (bevel objects)
- Translation, Scaling, and Rotation of the dataset
- Select named surface if dataset contains more than one

The plugin is being submitted to the Blender testing community and, once finalized, will be available as a supported plugin.
