Introducing the view model
Looking at view model classes

  • Let's look at which classes are involved in the view model

  • A VirtualUniverse defines the universe coordinate system

  • A Locale places a scene graph branch within that universe

  • A ViewPlatform (and a Transform3D above it) defines a view point within that locale
  • It defines a frame of reference for the user's position and orientation in the virtual world
  • Think of it as a magic carpet
  • There can be many ViewPlatforms in a scene graph
