2. Contents History What its based on: depth hints Stereoscopic picture Parallax – Positive parallax – Negative parallax – Parallax in the picture Production? – Side-by-Side rig – A beam splitter rig – Panasonic AG-3DA1 Post-production software Viewing/playback technologies – Passive technology – Active technology – Autostereoscopic technology Where to play Challenges

3. History 3D is not new Milestones: – 1890 – 1950 – 2000 1/18

4. What its based on: depth hints Monocular depth hints Binocular depth hints 2/18

15. Viewing/playback techniques Passive Active Autostereoscopic 13/18

16. Passive technique Left and right images interlaced Based on polarisation Used in USA – Requires an expensive silver screen 14/18

17. Active technique Right and left image take turns Shutter-glasses Double frame rate Glasses synced with infrared Used in europe 15/18

18. Autostereoscopic technique Placing the viewer is challenging (sideways/depth) Poor resolution Cannot respond to motion parallax. 16/18
