This uses ST_AsGeoJSON from PostGIS and supports 3D

http://postgis.refractions.net/docs/ST_AsGeoJSON.html

links to

http://openlayers.org/dev/examples/vector-formats.html

however I have not seen Openlayers in 3D only links

http://trac.openlayers.org/wiki/3D

Yup, I've seen the support in both PostGIS and OpenLayers, but it'll be nice to see it in Action. Perhaps a project for openstreet maps where they draw the roads per elevation, including bridges – dassouki Aug 25 '10 at 11:54
