  • 1. Stereoscopy(The Science Behind 3D) By: Pradatta Adhikary Pathikrit Modak Subhashis Pal Avishek Das Avijit Sarkar
  • 2. What is Stereoscopy ? Stereoscopy (also called stereoscopic or 3-D imaging) refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth.
  • 3. Binocular Vision
  • 4. Binocular Vision
  • 5. Stereoscopy Vs. Normal Image Ina normal image both of our eye sees the same picture But in a stereoscopic Image our two eyes sees two slightly different images, and that’s how illusion of three-dimensional depth is created.
  • 6. Stereoscope of Early Age
  • 7. Modern 3D Technology Modern 3D technology is divided into several procedure : With lenses:  Anaglyphic 3D (with passive red-cyan lenses)  Polarization 3D (with passive polarized lenses)  Alternate-frame sequencing (with active shutter lenses)  Head-mounted display (with a separate display positioned in front of each eye, and lenses used primarily to relax eye focus) Without lenses: Auto stereoscopic displays, sometimes referred to commercially as Auto 3D.
  • 8. AnaglyphDisadvantage Color depth is absent due to colored filter glass.
  • 9. Polarization 3D Used in modern 3D Movie theater.
  • 10. Alternate-frame sequencing
  • 11. Head-mounted display
  • 12. Auto Stereoscopy Used in Glassless 3D device like 3D Tab, 3D Mobile, Gaming Devices etc.
  • 13. 3D Gaming Now games are also available in Stereoscopy Every High performing graphic card is capable Converting any games into 3D A “3D Graphic kit” Required for that reason
  • 14. 3D Graphic Kit
  • 15. 3D Conversion
  • 16. YouTube 3D• Now with the growing popularity of Stereoscopy YouTube Also stated 3D video channels
  • 17. 3D Television Not only movie, now we can enjoy television program also in 3D. There are many television channels who telecast their program both in 3D & 2D.
  • 18. Stereoscopic Camera Unlikenormal camera stereoscopic camera uses two lenses representing each of our eyes.
  • 19. Sample 3D Photograph
  • 20. Future Need or not of 3D? Doesn´t add "not that much" of value to a film. New trends in Electronics market New 3D revival YouTube 3D Channel “After Toy Story, there were 10 really bad CG movies because everybody thought the success of that film was CG and not great characters that were beautifully designed and heart- warming. Now, youve got people quickly converting movies from 2D to 3D, which is not what we did. Theyre expecting the same result, when in fact they will probably work against the adoption of 3D because theyll be putting out an inferior product. ” —James Cameron
