From A Tutorial on Base Web Technologies CRPC Annual Meeting/NASA Langley/Trip to China -- May 14-17 June 10-13 1996 July 12-18 1996. by Geoffrey Fox
Basics:
  • VRML defines a set of objects that can describe 3D graphics - nodes.
  • Nodes are arranged in hierarchical structures - scene graphs
  • Scene graphs define the ordering for the nodes - the state of the scene graph depends on the earlier and affects later nodes.
  • Separators can limit the effects allowing parts of the scene to be isolated from other parts.
Nodes are characterized by the following information:
  • Kind of object: cube, sphere, texture map, transformation, etc.
  • The parameters that describe the object,
  • The optional name of the object,
  • For some types of nodes - group nodes - the child nodes can be specified
