2. Magic Eye

3. Crossviewing

4. Viewer crosses eyes, looks “through” picture, or uses a stereoscope Maintains color and brightness of original image

5. Advantages of Glasses Viewer does not have to learn a technique to see the image Viewer is not restricted to one viewing angle or distance Allows multiple viewers of the same image

6. Anaglyph

9. Polarization One way of presenting an image that will be blocked by one lens and allowed by another Popular in 3D movies today Solves color issues of anaglyph Projection technology is expensive

10. Alternate-Frame Sequencing

11. Head-Mounted Displays

12. Moving Away from Glasses Lenticular displays for printed media Parallax barrier: apply the same concept to electronic displays No need for glasses, but viewer’s position is restricted

13. Software that supports 3D Display 1.Blender:Blender A free and open source 3D modeling and animation application which can be used for modeling, UV unwrapping, texturing, rigging, water simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications.

15. Software that supports 3D Display 2. K-3D K-3D K-3D is free-as-in-freedom 3D modeling and animation software. It features a plugin-oriented procedural engine for all of its content, making K-3D a very versatile and powerful package. K-3D excels at polygonal modeling, and includes basic tools for NURBS, patches, curves and animation.

17. 3. Google SketchUp 6Google SketchUp 6 Google SketchUp is software that you can use to create, share and present 3D models. Whether you want to design a new deck for your house, build models for Google Earth, or teach geometry to your fifth-graders, you can use SketchUp to see your ideas in 3D. And when you’re done, you can export an image, make a movie or print out a view of what you made.

19. What is 3D display? A 3D display is any display device capable of conveying three-dimensional images to the viewer. The optical principles of multiview auto- stereoscopy have been known for over 60 years. However, practical displays with a high resolution have recently become available at much lower prices.  As a result, the commercialization of 3D displays for entertainment is receiving increasing funding.

20. Types of 3D displays Stereoscopic: Autostereoscopic: Computer-generated holography: Volumetric displays:

21. Drawbacks Each of these display technologies can be seen to have limitations, whether the location of the viewer, cumbersome or unsightly equipment or great cost. Overcoming the latter is perhaps the key challenge for the budding 3-dimensional imaging sector.

22. 3D Display and Its Application 3D Television 3D Game 3D Work Space Design and build things like building, car, etc. on 3D application.

23. Computer-Generated Holography Uses interference of beams of light to simulate the natural scattering of reflected light Technology to create static holographic pictures has been around since 1960

24. “Real” 3D Autostereoscopic displays Displays not limited to a 2D surface

25. Volumetric Displays Actually generate 3D images in 3 dimensions, using voxels instead of pixels Have much wider viewing angles than other types of displays Requires significantly more bandwidth for display data Size/space constraints and cost currently limit availability and practicality

26. Swept-Volume Displays Typically consists of 2 main parts: a rotating display surface and a projector Relies on persistence of vision to work

27. Static-Volume Display Consists of a 3-dimensional matrix of controllable elements The most direct approach to making a volumetric display

28. Current devices on the market Currently, there are none available to the general public However, lots of prototypes exist National Institute of Advanced Industrial Science and Technology Actuality Systems
