An Overview of Web-Based
3D Computer Graphics Standards
2D: Takes less power to compute, easier to encode and transmit;
But generally less expressive and compelling, viewer perspective limited by the dimension to the creators’ own
3D: More difficult to model;
But easier to manipulate from multiple perspectives and animate more realistic motions.
Birth: First proposed in a paper submitted to the First International Conference on World Wide Web
Popularization: Revamped as VRML 97; established as an ISO standard; became widely used, particularly for education and research area.
CyberTown.com’s 3D chat application developped by Blaxxun Software in VRML97 standard
“VRML was born dead. It never solved any real problems. Good riddance.”
--Clay Shirky, on the WWW Artist Consortium mailing list
“No integration with HTML, They were too busy getting the 3D to work.”
--Chris Phillips, director of business development and multimedia at Microsoft
Central idea of these criticism is: VRML gets the job done on 3D part, but its spec is locked, thus there is no easy way to integrate or extend it.
Multiple data encodings
New graphics features
New networking features
Improved APIs, more language/object model bindings
MPEG-4 has streaming interactive 3D using VRML
