GRASS 5
Creating a DEM from overlapping images
There is some old GRASS 5 software in
which does this job. It awaits integration into GRASS 6+.
Tutorial: http://grass.osgeo.org/gdp/stereo-grass/index.html
GRASS 6
- Viewing existing data as stereo 3D
The d.anaglyph addon module provides an easy way to create 3D anaglyphs and stereographs. It uses the m.nviz.image module to render two viewpoints, then from those two images composes the 3D image into a single PNG file. In time it should be possible to port this functionality into NVIZ itself.

- No special viewing equipment needed: just focus into the distance or cross your eyes.
- Here is a nice how-to-view article
