Thanks Chris, that's quite impressive.

My interest is in using this as a better alternative to the
OS open terrain data as a base over which maps and/or imagery
can be draped, a la Google Earth.  Whether it is better to
extract building outlines, and semantics such as the complex
OSM descriptions for roof shapes, or to just drape a 2D map
over a 3D terrain for display, is I think an open question.
