  1. How Do 3D Glasses Work? Caitlin Riddle 2005

  2. Types Of Paper 3D Glasses • Anaglyph • Pulfrich • Polarized

  3. What Can Be Seen In 3D? • TV • Movies • Video Games

  4. How Does Our Binocular Vision Work? • Binocular vision lets humans tell the distance of an object up to 20 feet • If you can see 20 feet away you have 20/20 vision

  5. How Does Binocular Vision Work Continued • Binocular vision is dependable on the distance between our eyes

  6. How Does Binocular Vision Work Continued • Each eye sees and image at a slightly different angle

  7. How Does Binocular Vision Work Continued • The brain takes the information from each eye and combines them into one image • Difference of angles makes image have depth

  8. How Do Anaglyph 3D Glasses Work? • The purpose of 3D glasses is to filter a separate image into each eye

  9. How Anaglyph Glasses Work Continued • On the screen, one blue image and one red image is displayed • The lenses only let one image into each eye

  10. How Anaglyph Glasses Work Continued • The red image goes in the red lens and the blue image goes in the blue lens (color separation)

  11. How are Polarized Glasses Different? • Polarized lenses are both a gray color and unlike anaglyph glasses, let color through • The lenses are specially cut at opposing 45 degrees

  12. How Do Polarized 3D Glasses Work? • Two images are projected on the screen and each one has a different polarization

  13. How Do Polarized 3D Glasses Work Continued • The polarized glasses allow only one of the images into each eye because each lens has a different polarization.

  14. How Are Pulfrich Glasses Different? • These glasses use the concept of one dark and one light lens to form 3D images

  15. How Can A Light And Dark Lens Form A 3D Image? • The image through the dark lens reaches the brain slightly after the image that went through the clear lens, creating a 3D illusion

  16. What Does LCD Stand For? What Is It used In? • LCD stands for Liquid Crystal Display • Lenses of the 3D shutter glasses are made of LCD panel

  17. What Are LCD Shutter Glasses? • LCD shutter glasses are a type of electronic 3D glasses • They are used to view 3D images on a computer screen

  18. How Do LCD 3D Glasses Work? • First, two images are displayed on a screen, each image for a specific eye • The images are shown rapidly

  19. How Do LCD 3D Glasses Work Continued • While the the image for the left eye is shown, the right eye is blocked by the glasses, and vice versa for the right eye

  20. How Do LCD 3D Glasses Work Continued • As you can see, each lens can be turned off separately • This happens extremely fast ( 60 flashes per second)

  21. How Do LCD 3D Glasses Work Continued • The lenses turn off and on so quickly that the brain just sees one 3D image that is the two images combined

  22. What Is Interlacing? • Interlacing is a computer technique used in viewing a 3D image on the monitor

  23. How Does Interlacing Work? • Interlacing is when the 3D image has alternating rows of pixels

  24. How Does Interlacing Work Continued • With this technique, pixel rows 1,3,5,7, and 9 would go in one lens and the even numbered pixels would go in the other lens

  25. How Does Interlacing Work Continued • While the odd numbered pixels travel through one lens, the other lens is turned off and vice versa

  26. How Does Interlacing Work Continued • The lenses turn off and on so rapidly the brain combines the pixels going into each lens into one 3D image

  27. What Are Pixels? • Pixel stands for picture element • A pixel is a single point in a graphic image • Pixels are divided in rows and columns

  28. The 1st Generation Of 3D • Computers began to be able to accommodate 3D images • You could not view the images with 3D glasses

  29. The 2nd Generation Of 3D • Altered the appearance of 3D games on computer images • The computer could load 3D images, but the loading time was extremely slow

  30. The 3rd Generation Of 3D Continued • Modified 3D graphics so they formatted the computer better • The pictures were of better quality

  31. The 4th Generation Of 3D Continued • The images are now transferred by a graphic card to the computer • The pictures are also great quality and clear

  32. The Types Of LCD Shutter Glasses • Wireless • Lightweight • Cheaper, simpler types

  33. The Brands of LCD Shutter Glasses • X-Force 3D Game Glasses • Sega 3D Glasses • 3D Magic • Crystal Eyes • Cyber Boy

  34. What Are HMDS? • Stands for Head Mount Display • Is a type of helmet device used for 3D viewing • There are displays inside the device that display the images

  35. About Me • Hey. I’m Caitlin Riddle and I’m 13. I love UNC and grilled cheese sandwiches are my favorite food. I play softball & volleyball. I swim too. I sing, play piano, saxophone, and guitar.
