Up: 2 Preliminary Investigation
Previous: 2.1 Introduction
The cameras used for the experiment were two of the webcams that SGI shipped
with its Indy range of workstations (dubbed Indycams, Figure 1).
These were preferable those that come with the
cams, Figure 2) for simple
logistical reasons -- it's very easy to strap two of the Indy cameras together
(``back to back''), with the lenses being separated by a good approximation
to a typical human eye separation (Figure 3).5
The most important detail here is that the cameras are laying on their sides;
the images obtained from each need to be rotated
and counter-clockwise as appropriate.
