2. Overview
What is 3D internet?
Applications (why 3D internet is important)
History (where we’ve been)
Current Status (where we are)
The Future (where we’re going)
3. What is 3D internet?
Combination of two powerful forces
• the internet
• 3D graphics
The result: interactive, realtime 3D
graphics delivered over the web.
4. Why now?
Until recently, there were two problems:
• slow computers
• slow connections
Downloading 3D content took a long time
Once downloaded, it ran very slowly
Quality of the graphics was poor
5. What’s Changed?
Increased bandwidth into the home
• cable modems
• DSL
Increased processor speed
• 1 ghz and beyond
Graphics accelerators
• installed on all new machines
• able to provide fast, high-quality graphics
6. Applications
E-commerce
• product visualization
• 3D virtual shops
• interactive demos
• 3D “banner ads”
Training
• web-based training using interactive 3D
7. Applications (cont’d)
Games
• multi-player, fully 3D (e.g. Sony Everquest)
Entertainment
• streaming 3D animation (much lower
bandwidth than video, can run full-screen, can
have interactivity)
Social Interaction
• 3D chat spaces
8. Applications (cont’d)
Education
• virtual “field trips”
• distance education as well as on-campus
• virtual “experiments” for physical sciences
• historical recreations for social sciences
• 3D data visualization for various fields

10. Design
How can 3D help me convey my message?
What visual form should the 3D content
take? (What is my metaphor?)
What kinds of 3D objects are needed?
How will they move?
How will the user interact with them?
11. Animation and Interactivity
Can be created in 3D authoring application
and exported
Can be created in a separate authoring tool
(e.g. Pulse, Cult3D)
Can be created using standard Javascript
(Blaxxun3D, Shout3D)
Advantages and disadvantages to each
approach
12. Polishing
Add sound, music if appropriate
User actions should often have sound
Put in context by creating a surrounding
HTML page
Add links to additional information pages
13. The Content Creation Team
3D modelers
• fairly specialized skill
• different modelers know different packages
• can also create 3D content from scanning
• 3D “clip art” also available
2D artists
• probably already in-house for web page art
• generally use PhotoShop or PaintShop Pro
14. Content Creation Team (con’td)
Sound/music specialists
• probably available in-house
• must adapt skills to Web3D context
Animators
• often same as modelers
• must be able to design for interaction
Programmers
• Javascript, Java both common
15. Example -- Forest Walk
Forest created by Andrew Reitmeyer for the
VRML Dream project
Simply uploaded the VRML file to a web site
and wrote a short HTML page to use
Shout3D’s “walk” viewer applet on it
Total time -- 10 minutes!
Building the forest itself took a bit longer
16. Here’s the HTML
<body bgcolor="#000000" text="#FFFFFF">
<center>
<applet width=300 height=250
codebase="../common/shout3d"
archive="shout3dClasses.zip"
code="applets/WalkApplet.class">
<param name=src value="forest.wrl">
</applet>
<br><i>Use the mouse to walk through the world</i>
</center>
</body>
17. Key Points
Simple 3D web sites can be easy to create
Good 3D content can be compelling
You need to build a good team
Try to leverage existing 3D content
wherever possible
