GRASS 5

Creating a DEM from overlapping images

There is some old GRASS 5 software in

http://grass.osgeo.org/outgoing/grass5/ → stereo

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.


Anaglyph

Red/cyan anaglyph created with the d.anaglyph module
       

Stereogram

Stereogram with fiducials created with the d.anaglyph module (requires stereoscope viewer)
