What
are VR panoramas?
Virtual
Reality Panoramas provide the dynamic viewing potential
of video without the prohibitive file size. Essentially,
they represent a 360 degree view from a single position.

By manipulating computer controls of the
panorama, viewers can look at any part of the 360 degree
scene, and zoom in and out to see more detail.

How
are they created?
The
most common method of creating panoramas is to take a series
of overlapping photographs from a stationary tripod.

These
photographs are digitised and stitched together using software
like Apple's QuickTime VR Authoring Studio. The result
is a rectangular image which has been distorted in such
a way that it will give the impression of perspective when
viewed as a cylinder.

In
the final step, the image is stitched into a cylinder, which
takes the form of a QuickTime VR movie. The movie from the
