Aldo use his SPi-V engine, based on Macromedia Shockwave.
Yes, that's right, thanks for pointing that out... It's currently in private beta. Expect news in august/september.
The SPi-V engine uses 3d hardware accelleration to provide smooth panning (and lots more)
you can get this effect also with PTViewer. Use the "mass"-parameter.
Oddly enough, the mass parameter influences exactly the opposite aspect of inertia.
In PTViewer, using the mass parameter, inertia is applied while panning, seemingly making the panning less responsive. When you release the mouse, the motion still stops abruptly.
In SPi-V, inertia 'kicks in' when you release the mouse. The motion 'fades' out. This way, the panning motion is as responsive as you'ld expect, but you won't get the abrupt stop you get with most viewers.
I did an experiment, showing people both a version with and without inertia. Once respondends had seen/'felt' the inertia enhanced panoramas, they no longer liked navigating the 'stiff' panoramas, saying it felt unnatural.
Another mill panorama for the non-Dutch ;-)

In this scene, the 'wings' of the mill were turning at up to about 2 seconds per revolution. That's about two wings passing per second. An impressive event even for me, these wings are quite large and heavy. I had to synchronise my (philopod) shooting with the revolutions of the wings in order to get the shadows right. I'll probably try to bring in a bit more motion blur into the wings at some time...
