Introduction

• Given current technological advancements in
  desktop computing interactive 3D models of
  objects and 3D Virtual Environments (VEs) can be
  experienced through the Web, using the hardware
  that can be found in common, low-cost personal
  computers.
• 3D web content is being deployed in a variety of
  applications education training, ecommerce,
  architecture and virtual cities, virtual
  communities and virtual museums

Intro. Cont.

• This presentation is designed to introduce you to
  the concepts and techniques of adaptive 3D Web
  sites.
• It will provide an introduction to 3D Web sites,
  with an overview of the major application areas
  and mentioning the main technologies,
  concentrating on standard ones.
• The adaptivity section will provide the context
  of 3D Web sites by first looking at analogies and
  differences with respect to Web-based hypermedia,
  and then discussing the problems of modeling and
  adaptation.
• In the Architecture for Adaptive 3D Web sites it
  will describe an example of a full architecture
  for adapting 3D Web content.
• A case study will then be considered in the
  domain of e-commerce.
• The conclusion will discuss current research
  challenges and directions.

3D Web BasicsDefinitions

• Web3D technologies The languages, protocols and
  software tools that make it possible to build 3D
  models of objects and 3D VEs that can be
  experienced through the Web, using common
  personal computers
• Complex 3D Web content virtual cities,
  visualizations of scientific data, and virtual
  museums.
• Web technologies content (represented in a
  proper format) is stored on a server and is
  requested by a client (typically, through HTTP),
  where it is displayed by a browser, or, more
  often, by a plug-in for a traditional Web
  browser.
• 3D Web content can be strongly integrated with
  existing Web content, both by augmenting Web
  sites with 3D interactive content (e.g., a 3D
  model can appear into a Web page together with
  HTML content) and by displaying most types of Web
  content (e.g., images, sounds, videos) inside a
  3D VE accessible through the Web.
• Note most Web3D technologies neither require
  nor preclude immersion, and 3D Web content can
  also be experienced with the input/output devices
  of today's common personal computers (i.e., CRT
  or LCD monitor, keyboard and mouse).

3D Web BasicsApplications and motivations

• Learning and Training
• E-commerce and Product Visualization
• Virtual Museums
• Architecture and Virtual Cities
• Virtual communities

Learning and Training

• Most important application areas for 3D Web
  sites.
• 3D VEs offer the possibility to recreate the real
  world as it is or to create completely new
  worlds, providing experiences that can help
  people in understanding concepts as well as
  learning to perform specific tasks
• Tasks can be repeated as often as required and in
  a safe environment

L T Cont.

• Employing 3D graphics allows for more realistic
  representations of subjects or phenomena,
  offering the possibility of analyzing the same
  subject from different points of view.
• This is important in the medical education domain
  where 3D reconstructions of parts of the human
  body

E-commerce and Product Visualization

• 3D Web store advantatges if properly implemented
  
• it is closer to the real-world shopping
  experience, and thus more familiar to the
  customer
• it supports customers natural shopping actions
  (such as walking, looking around the store,
  picking up products,),
• it can satisfy emotional needs of customers, by
  providing a more immersive and visually
  attractive experience
• it can satisfy social needs of customers, by
  allowing them to meet and interact with people
  (e.g., other customers or salespeople).
