To all,
A friend of mine needs to submit a picture (rendering?) showing how a
proposed berm would look at a shooting range. I'm getting this third
(or fourth!) hand so I don't have any more details on the request.
My first thought was to use something like Google Earth and a 3d
model of the berm and take a screen snapshot when I maneuvered to a
viewpoint I liked. But the available DEM and imagery are of such low
resolution it would not be adequate (and I think it violates the license
agreement). Similarly, unless I get much better DEM and imagery (and
that's not likely), terrain modelers like VTP (http://vterrain.org) or
"terrain capable" 3D modelers like Sketchup would not give enough detail.
So how about augmented reality? I could take a photo of the area
using a smart phone, and maybe get position and orientation out of it
somehow (perhaps determine focal length too). But I don't know of any
FOSS projects for rendering 3d models onto real photos.
Any ideas?

Brent Fraser
