Thanks for your patience Woolwell-and I trust I'm not trying it! Before this turns into a marathon, I'll bite the bullet and confess I saw the add-on in the current issue of Web User.Admitting I'm a parasite, I was thumbing through it in WH Smith's and didn't purchase it. Anyway, I assumed it created a 3D image, but I didn't see anything about wearing the necessary goggles.....perhaps I missed that?
I used to view true aerial 3D images using a stereoscope. The imagery that Google uses for Earth/Map cannot produce true 3D. By using perspective it can give a feeling of 3D. The other view is using calculations to give a 3D look.
I'll now have to have a look at Web User as I cannot find anything on their site.
