Looking for current information on "object" based panorama technology (i.e. camera looking in, not out)

Hello,

I used to be very involved in QTVR, iPix (even VRML!) years ago, but it's been around 8 years since I've done anything in this space.

However, I now have a need to do some projects that will involve VERY large QTVR type objects. What I mean is that instead of the image being projected on a virtual sphere with the viewpoint in the center, I need the object in the center and the view-point revolving around that center point.

I've been googling for the better part of a day, and it seems that no one cares about that any more. :( Everything I see is panorama (i.e. looking out)

I have found some small scale turntables, etc. for e-commerce type work, but I'm not seeing what I'm looking for...

I need an authoring and delivery environment that can work with very high-rez images that will allow deep-zooming, but that handle it intelligently so that it minimizes bandwidth on the delivery side (i.e. I don't want to have a client/browser download gigabytes of data before it works).

I've seen some amazing examples of what I'd like here http://www.panoramas.dk/archive.html, however I'm not seeing anything to help me on the "object" VR side.

Can someone point me in the right direction to find out what the current best-in-class solutions are for this problem? I don't want 5-6 year old technology, and that's all Google is finding for me. I want modern, standard-complaint (HTML5?) delivery, bandwidth friendly, etc.

Thank you very much for your help!
