From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)


Nodes can be named, and used repeatedly
  • DEF MyCylinder Shape { }
  • USE MyCylinder
DEF node-name node-type {}
  • node-names are a sequence of characters and they are case sensitive.
  • Do not used the names which are already in use for specific purposes as a node name.
USE node-name
  • It is possible to use the same node in the same file multiple times without repeating the definition. There is no limit for instancing the same node by using USE.
