Passive Stereo Screening

To screen the footage, a passive stereo format shall be used.  The technique involves the use of inactive polarised glasses, two projectors with corresponding filters and a software patch that synchronises the footage.

The passive stereo setup has various attributes that out benefit the use of other 3D screening formats, some of which include;

• The glasses make viewing more available.  Shutter glasses are much more expensive, limiting the number of users
• Frames per second (fps) is not restricted.  Active forms of stereo required a high fps (at least 60fps) to create the effect
• Stereoscopic footage can be quickly reviewed during production
