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
VRML2.0 Field and Event Reference
In addition to other changes from VRML1, VRML 2.0 introduces a couple of new field types:
  • An SFInt32 field (formerly SFLong) contains a 32-bit integer. An MFInt32 field contains a list of 32-bit integers.
  • An SFNode field contains a node (or rather, a pointer to a node). An MFNode field contains a list of pointers to nodes.
  • An SFTime field contains a double-precision floating point value indicating a number of seconds since 00:00:00 Jan 1, 1970 GMT.
SFEnum (use SFString) and SFMatrix from VRML1.0 are deleted
