This document discusses 3D technology, including its history and various types. It begins with an introduction to 3D displays and how they create moving objects in three dimensions. The history of 3D technology is then reviewed, noting the 1844 stereoscope and 1855 kinematoscope as early 3D cameras. Different 3D technologies are described, such as anaglyph, polarized, and active shutter 3D. 3D cameras and scanners are also covered, with 3D cameras using two lenses to capture stereo images and 3D scanners using lasers to scan and model real-world objects. Applications of 3D technology are growing in areas like graphics, modeling, mobile devices, architecture, and medicine.
how 3d technology works
- 2. CONTENT Introduction History of 3D technology Different types of technology 3D Camera 3D Scanners
- 3. INTRODUCTION A 3d display is a screen that shows a three dimension Picture •It is a visual representation system that tries to create moving Objects in the third dimension
- 4. In simple that we have feel that whatever happens in 3D effect it is part of our real life.
- 5. History of 3d technology In 1844 David Brewster introduces the stereoscope (3d camera) In1855 the Kinematoscope invented (3d video camera)
- 6. Stereoscope (3D camera) Kinematoscope (3D video camera)
- 7. Audience wearing special glasses watch a 3D "stereoscopic film" at the Ambassador Hotel Theater in Los Angeles on 27 September 1922
- 8. HOW IT WORKS To understand the basic 3D technology techniques, we must have an idea about the 3D glasses. At present, there are around two main kinds of 3D glasses technologies which are called as active and passive.
- 9. Different Types of 3D Technology • anaglyph 3D technology • polarized 3D technology • active 3D technology • parallax-barrier 3D technology
- 10. Anaglyph glasses • The purpose of 3D glasses is to filter a separate image into each eye
- 11. Anaglyph glasses In this system, two images are displayed on the screen, one in red and the other in blue (or green). The filters on the glasses allow only one image to enter each eye, and our brain does the rest
- 12. Anaglyph glasses
- 13. Active shutter 3D The active shutter glasses required for the 3D technology is categorized into two main kinds which are called as… liquid crystal shutter glasses display glasses.
- 14. Active shutter 3D Used at HOME THEATER. Image Looks Great. There is a battery in it.
- 15. Active shutter 3D Glasses
- 16. Active shutter 3D • when the TV is showing an image for the left eye, the left eye's shutter will be open and the right eye's shutter will be closed. • A fraction of a second later the TV will refresh to show an for the right eye, and the right eye's shutter will open and the left eye's shutter will close.
- 19. passive polarized 3d glasses Two of the presently used are passive 3D glasses are.. linearly polarized glasses circularly polarized glasses.
- 20. Images of passive 3D glasses
- 21. passive polarized 3d glasses Two images intended for each eye are displayed from two separate projectors. Each image is projected with a polarization mutually orthogonal to the other polarization. Polarized 3d glasses are then used with polarized filters to ensure that each eye receives only the intended image. It works well, and the required glasses are cheap and light.
- 22. How Do Polarized 3D Glasses Work? • Two images are projected on the screen and each one has a different polarization
- 23. How Do Polarized 3D Glasses Work The polarized glasses allow only one of the images into each eye because each lens has a different polarization.
- 24. PASSIVE 3D V/S ACTIVE 3D PASSIVE 3D ITS CHEAP.. PASSIVE 3D DOSE NOT REQURED CHARGING.. THESE GLASSES ARE LIGHT & EASY TO USE.. NO HARMFULL EFECTS… ACTIVE 3D ITS COSTY.. ACTIVE 3D NEEDS TO BE CHARGE BEFORE USE.. THEY ARE HEAVY IN COMPARISION OF PASSIVE 3D. PEOPLE COMPLAIN ABOUT HEADACHE .
- 25. Autostereoscopy Auto 3-D, more formally known as auto-stereoscopic imaging, is a display technology that enables a 3-D (three dimensional) effect without requiring the viewer to wear special glasses.
- 26. Autostereoscopy autostereoscopic displays technology include….. lenticular lens parallax barrier volumetric display holographic light field
- 27. Parallax Barrier
- 28. Parallax Barrier • Parallax-barrier technology requires a barrier in front of a screen. The screen shows both the left and the right images, and the barrier effectively has slits in it that separate them out. If you look at the image from exactly the right spot, the slits will allow the left image through to your left eye, and the right image through to your right eye, with no overlap.

- 32. 3D Camera A 3D digital camera is a camera that is capable of taking pictures in 3D. 3D cameras use two lenses so two images are captured with the right and left lens at the same time.
- 33. 3D CAMERAS (3d-camera) Range imaging is the name for a collection of techniques which are used to produce a 2D image showing the distance to points... 3D cameras use two different lenses to shoot video or any object which are at same camera
- 34. 3D Camera • camera has two lenses and two CCDs imagers that capture a scene much like your regular digital camera does, except, just like you have two eyes, the camera captures two scenes – one through each of the two lens/ccd configurations. so, instead of seeing a single two- dimensional flat image like a regular camera, the 3d camera shows two images, from two different points of view, and when combined and viewed appropriately, displays a stunning depth only available from 3d content!
- 35. 3D Camera
- 36. 3D Scanner A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance.
- 37. 3D Scanner • 3d scanning is a process which a physical object will be placed on the base of a 3d scanner and it will then be circled and scanned by lasers with surrounding pieces of a 3d scanner
- 38. 3D Scanner The surrounding pieces of this scanner will encircle the model and the scanner will process what the object looks like and 3d file constructed around the physical object itself.
