GRASS 5
There is an old GRASS 5 software in http://grass.osgeo.org/outgoing/grass5/ -> stereo
which is doing this job. It is yet awaiting integration into GRASS 6.

GRASS 6
There is a d.anaglyph addon module for an easy way to greate 3D anaglyphs for use with red/cyan glasses. It uses the m.nviz.image module to render two viewpoints, then from those composes the 3D image into a PNG file. It should be possible to port that functionality into NVIZ itself.
