Foil 8 VRML1.0 to VRML2.0 Transition

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 98. by Zeynep Ozdemir, Rob Baker, Meryem Ispirli, Geoffrey C. Fox
After an Interesting "competition", a new standard VRML2.0 was adopted in May 1996. After some uncertainty, it appears that this standard will be accepted by major players
  • Good VRML2.0 browsers are (starting Spring 97) available
Conceptually it is in most areas similar to VRML1.0 but there are many changes in detail and VRML1.0 is NOT a subset of VRML2.0 (MOST of language is changed)
Major goal of VRML2.0 was to support dynamic 3D worlds where components of world move relative to each other and interact together
  • This is achieved by events in VRML nodes which are linked by "routes" and invoked by time stamped animations or Java/JavaScript programs
