Foil 5 Open Inventor -- Nodes

From VRML and Use of Databases as backend and Application to GIS ARL Database Tutorial -- February 98. by Krzysztof Walczak
The node is the basic building block used to create three- dimensional scenes in Open Inventor. Each node holds a piece of information, such as a surface material, shape description, geometric information, light or camera.
The Open Inventor nodes can be grouped as follows:
  • Shape nodes - representing 3D geometric objects
  • Property node - representing appearance and other qualitative characteristics of the scene such as material, lighting model, textures, or environment
  • Group nodes - containers collecting nodes into groups
  • Engines - can be attached to other nodes and drive animation or impose constraints
  • Sensors - detect changes in the scene database and invoke suitable notification/callback functions
