Thanks :) The parasol should really also have some cloth dynamics (sag) to look
realistic.
And the reflections are rendered, with a spherically mapped background panorama which
also contributed a little for the lighting (GI) - but not much.

Yes, but unfortunately it costs quite a lot to build and print.. I have a good contact
with a company who makes such tents, but so far they are not too happy to pay for a
"test", although they are interested in the results.

It's a flat plane, mapped with a texture from the bottom cube face (or was it front
mapped - I don't quite remember..) A moving camera is not really possible inside a
panosphere without losing the illusion, so you can see the background slides a little
when the camera moves into the tent.

Thanks for the offer, but you don't have to do that. I typically use PTadjust to remove
the tripod from the nadir shot with a 110 degree fov square, and then I end up with lots
of temporary down-shots in my temp folder, which can be very useful for texture mapping.
Using standard photos for ground maps can always be tricky because you need to be a
little up in the air to get more than a little piece of it, and there is always a problem
with not getting your own feet into the photo. Extracting from panos is much easier and
better :)

Yes it is, but you only saw the flat parts..
I love Holland BTW, particularly your "Venetian" cities, like Amsterdam and Delft :)
