Tony, just a question - Why the map tilting and fade when the panorama loads?
The transition into Streetside imagery is so seamless. Since they already use cubic projection for their panoramas and the ICE panoramas that Photosynth hosts also use cubic projection, why not just re-use that transition?
I realise that Streetside is also pulling simplified local geometry along with the panorama cube and DZIs and the ICE panoramas have no local geometry in many cases, but I remain curious.
I would be perfectly happy to zoom down to the bottom face of the cube and let the virtual camera swing up to the horizon as the sides of the cube fold up around us, even if the panorama is not a 360 degree wraparound.
