[GRASS-user] 360 degree view from a given point

[Ludwig Max Brinckmann]

Just browsing through the web I found the following new product
http://www.viewranger.com/vrproductinfo.php, which is a mobile phone map
(nothing new here), but it also offers
'Unique 3D Panoramic Viewpoint Maps show you what you see!', which is
basically an annotated 360degree view of the surroundings of a given
point, where the current location is transmitted from a GPS to the phone.
(I have no affiliation with this product whatsoever, and I have never tried
it: I would wonder how they would know which direction a user is facing at a
given moment, the GPS will not give it - for most parts of England it is
also easy to implement: just return a flat horizon ;-) I did think however,
it is quite an inspired application)

I have a webmap (www.yunnanexplorer.com/map), that I would like to enhance
with the option of clicking a point and then getting a full 360 degree view
from this point and surface elevation, a bit like 360 degree cameras to
display with the map.

I have seen the recent GRASS integration with a python CGI script, so that
would be a starting point to generate the image from a client webbrowser.
I have played a bit with NVIZ in the past, but my question to the grass
experts is: what would be the best way to do this in GRASS?
