Now I am on the computer where I was playing with these VRML models, I can confirm that the viewer I was using was ParaView http://paraview.org/ I've just checked, and it can export to POV-Ray format, the open source ray tracing software which can be used to produce very high quality rendering.

I used the vrml export from Loch to produce a 3D model file which was suitable to get 3D printed. The article about it (written by Mike Bedford, who got the printing done) is in the latest issue of Descent magazine. I could import that model file into other 3D modelling software, so perhaps there is an application out there which can convert it?
'meshlab' looks like a good tool for doing this http://meshlab.sourceforge.net/ (already packaged in Debian). I expect blender can too, but some goolgeing suggests that this needs extra scripts.
The wavefront .obj file seems a fairly straightforward format: http://en.wikipedia.org/wiki/Wavefront_.obj_file#File_format
But it only represents surfaces so far as I can see, not lines. So we can export terrain and volumes, but not plain surveys (without faking survey lines into cylinders).
It does look like this would be a useful format to output. Or teach meshlab to read/write .3D and/or lox.
Do Bruces' mates know that Aven can export a video file directly, animating a survey? However that can only have a mesh surface (as generated by terraintool) currently, which may or may not be 'high quality' enough for their purposes.
