  1. 3D Technologies for the Web

  2. Agenda • Motivations for providing 3D web content • Technologies • 3DML • VRML • Shockwave 3D • Development Tools and Processes • Deployment Issues

  3. Motivations for 3D Content • Virtual Tours ( Environments, Architectural walk-thru ) • Product design presentation and interaction • Scientific applications - molecular structures, navigation of ‘spaces’ • Abstract representations of real-world concepts, e.g navigating file structures or data warehouses via real-time 3D metaphors. • Online gaming

  4. Technologies • VRML • Shockwave 3D • 3DML

  5. 3DML • .3dml file has a mark-up syntax similar to HTML • Worlds called ‘Spots’ constructed from Blocks • Blocks have different characteristics which determine how they can be used in the construction of the 3DML world. • Blocks for: • Navigation • Textures • Animated GIFs • Latest version supports video streaming

  6. 3DML • Only supported on the Windows Platform • Blocks are regular shapes so difficult to represent circular structures • Download client from www.flatland.com

  7. VRML • Virtual Reality Modeling Language, or sometimes called 'Virtual Reality Markup Language’ • Script-based language for defining desktop 3D environments. • VRML worlds can be constructed by hand in a text editor • More commonly produced from a 3D world created in a modeling package, like 3D Max or Maya • Exported in VRML format. Each camera that is defined within a 3D modeling package becomes a viewpoint in the exported VRML world. This helps to provide a means to control position and navigation within the world. • Files have .wrl extension • Worlds viewed in VRML client - usually within Web Browser • VRML is a desktop VR solution as compared with immersive VR

  8. VRML -Create Model

  9. VRML - Example Script VRML V2.0 utf8 # Produced by 3D Studio MAX VRML97 exporter, Version 2.05, Revision 1.3 # Date: Thu Oct 28 15:11:58 2004 DEF Sphere01 Transform { translation -32.45 0 -41.79 children [ Shape { appearance Appearance { material Material { diffuseColor 0.8392 0.898 0.651 } } geometry Sphere { radius 27.82 } } ] }

  10. VRML • Supports event sounds and placing of spatial sounds within world • Supports video texturing of objects • VRML 1.0 emerged in mid 1990s • VRML 2.0 (1997) supports the embedding of animation of objects from 3D modeling environments when exporting to vrml giving so-called ‘moving worlds’

  11. Shockwave 3D • Collaboration from Macromedia and Intel • Available with Macromedia Director since version 8.5 • Lingo scripting language extended to include • functions which can create and manipulate a 3D • world and objects contained within.

  12. Shockwave 3D • Models created in applications such as 3D Studio • MAX and exported out to .W3D format. • Free plug-in for a number of 3D development • software packages such as MAX and Maya • Fairly heavy client required (4MB) • Lots of good content out on the web

  13. Deployment Issues • Client-side software required to view & navigate worlds • Bandwidth! - broadband take-up and capacity will determine the future potential for 3D on the Web.

  14. Also Have a Look at Blaxxun 3D • Blaxxon VRML / Java based 3D developed by Blaxxon Technologies ( Windows Only). www.blaxxun.com
