Students (who did all the work)
Project title: Game engine customisation.
The aim of this project was two-fold, firstly to modify the Torque game engine to support passive (side-by-side) stereoscopic projection, the second was to interface it to a Polhemus tracking system and a "Gypsy" motion capture suit.
The motion tracking hardware was provided by Company in Space (CIS). For various reasons the Polhemus (magnetic tracking system) was not fully implemented (It had limited range and was not wireless). The implementation using the Gypsy suit is shown in all the image on this page.

The stereoscopic projection (DLP projectors and silver front projection screen) and computer (nVidia FX3000 dual display graphics card) was provided by the visualisation theatre at the Centre for Astrophysics and Supercomputing, Swinburne University. The passive stereo projection places the left eye view on one display of a dual display card, the right eye image is placed on the other display of the card. These two displays are projected using two DLP projectors whose images are overlaid on the projection surface, aligned to within a pixel.
