Magic Eye
• Viewer crosses
eyes, looks
picture, or uses
a stereoscope
• Maintains color
and brightness
of original image
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
• 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
Alternate-Frame Sequencing
Head-Mounted Displays
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
Software that supports 3D Display
1. 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.
Software that supports 3D Display
2. 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
3. Google 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.
What is 3D display?
• A 3D display is any display device capable of
conveying three-dimensional images to the
• The optical principles of multiview autostereoscopy have been known for over 60 years.
• However, practical displays with a high resolution
have recently become available at much lower
 As a result, the commercialization of 3D displays
for entertainment is receiving increasing funding.
Types of 3D displays
Computer-generated holography:
Volumetric displays:
• 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.
3D Display and Its Application
3D Television
3D Game
3D Work Space
Design and build things like building, car, etc.
on 3D application.
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
“Real” 3D
• Autostereoscopic displays
• Displays not limited to a 2D surface
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
Swept-Volume Displays
• Typically consists of 2
main parts: a rotating
display surface and a
• Relies on persistence of
vision to work
Static-Volume Display
• Consists of a 3-dimensional matrix of
controllable elements
• The most direct approach to making a
volumetric display
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
•Actuality Systems
