2. Trends and Vision Next generation displays will be 3D Black&White  Colour  High Definition TV A paradigm shift in visualization The market is waiting for a real solution 3D data is already there, but lost while displaying

3. Background 3D images contain more information than 2D Stereoscopic: 2x (L+R) Multiview: ~8-16x Volumetric: 20-200 slices True 3D: continous (~100x) Total number of beams law, points/sec rate Determine the quality of any 3D solution Direction selective light emission Common for all 3D systems having a screen 3D Display Technologies

4. Fundamentals Additional independent variant to X, Y : Φ Emission range: FOV Number of independent beams in the range: Angular resolution Φ = FOV / n Angular resolution determines FOD

5. Fundamentals Vertical / horizontal parallax Reduce the number of beams by omitting vertical parallax Different horizontal and vertical angular resolution

6. The HoloVizio System Optical modules Project light beams to the points of the screen from various angles Holographic screen Direction selective property with angularly dependent diffusion characteristics Emission angle geometry determined The screen performs the necessary optical transformation, but makes no principal change in directions No optical road-blocks like at parallax barrier, lenticular lenses

7. The HoloVizio System Specific distributed image organization A module is not associated to a direction Each view of the 3D image comes from multiple modules Smooth and continous transition between views Light field reconstruction instead of views

8. The HoloVizio System HoloVizio image synthesis Spatially addressable light-rays 2D + Angular resolution Horizontal (vertical) parallax Scalability High pixel count Any aspect ratio From small to large scale systems Price / Performance Possible to build perfect 3D displays

10. HoloVizio Displays The world first glasses-free 3D cinema system: HoloVizio C80 3,5 m dia Holoscreen (140”) No glasses, no optical contradiction LED based 3D projection unit Exceptional 1500 Cd/m2 brightness 40 degrees FOV 2D compatible Fitting cinema rooms, 3D simulators

11. HoloVizio SW System Integrate existing applications / display 3D models in real-time Interactive applications Display pre-rendered 3D models High quality images Display real-life 3D scenes Light field streaming

12. Integrate Existing Apps OpenGL wrapper for HoloVizio display systems User computer Legacy OpenGL Application OpenGL Wrapper OpenGL Display driver 2D display HoloVizio

13. Display Pre-Rendered 3D 3D display HoloVizio Converter HoloPlayer Favourite Renderer HoloVizio scripts

14. Live 3D transmission Linear camera array 27 cameras 640x480 at 15 FPS 960x720 at 10 FPS Camera calibration Mapping of camera pixels to light rays Transmission Video streams 100 Mbit now, 30 Mbit with H.264 Display Any HoloVizio display

15. COHERENT project To create a networked holographic platform to support multi-user real- time collaborative 3D interaction between geographically distributed teams. To create two innovative applications: a collaborative medical visualisation system a collaborative design review system for the automotive industry  Large-scale HoloVizio

16. HOLOVISION project To realize a >100x capacity jump of current displays real technology challenge to build a no-compromise display a milestone towards Gigapixel displays To realize a novel principle combination of spatial and time multiplexing to fully exploit component capabilities To use latest available technologies and components Hi-res microdisplays, LEDs  World’s first 100 MPixel 3D display

17. OSIRIS project Glasses-free 3D cinema prototype 2 nd generation desktop monitor Real-time Light-field capture

18. MUSCADE project The MUSCADE project defines, develops, validates and evaluates the technological innovations in 3DTV capturing, data representation, compression, transmission, rendering and display adaptations required for a technically efficient and commercially successful 3DTV broadcast system.

19. DIOMEDES project DIOMEDES focuses on new methods for the compression and delivery of multi-view video and multi-channel audio to users. The DIOMEDES approach is to develop a 3D Peer-to-Peer (P2P) distribution system, which will be designed jointly with novel video compression techniques. The compression, distribution, and security technologies developed within DIOMEDES will be demonstrated in the form of an integrated test bed.

20. 3D VIVANT project The 3D VIVANT project investigates the possibility of using different technologies for capture and display of 3D content For capture, 3D VIVANT takes full advantage of 3D Holoscopic imaging technology, where a single camera is required For the display, the project takes advantage of the hologram geometrical principles to provide immersive, ultra high resolution presentation of 3D content
