2.2 Method

Figure 1: An Indycam.

The cameras used for the experiment were two of the webcams that SGI shipped with its Indy range of workstations (dubbed Indycams, Figure 1).

Figure 2: An O2-cam.

These were preferable those that come with the \( \textrm{O}_{2} \) workstations (dubbed \( \textrm{O}_{2} \)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

Figure 3: A stereocam formed by two Indycams (Figure 1) strapped back to back.

The most important detail here is that the cameras are laying on their sides; the images obtained from each need to be rotated \( 90^{\textrm{o}} \) clockwise and counter-clockwise as appropriate.
