Andrea, I'm afraid I don't know the answer to that one. All the OSG terrain options take a regular grid of height postings as input, so you would probably need to preprocess an arbitrary could if you want to go that route. osgdem, osgEarth, etc. all use GDAL under the hood to read data formats; you might explore the GDAL utilities (http://remotesensing.org/gdal) and see it there's a pathway there.
Once you have regular gridded data in a known format, you can use either osgdem/VPB or osgEarth to create your terrain (you don't need both in this case). Wish I could be of more assistance.
