Techniques of Perception in VRML97
by n_polys 08_2001

Existential Perception
What can I do in this world? What is my relation to this environment?
  • NavigationInfo: AvatarSize, Headlight, visibilityLimit, type, speed
  • Timesensor: cycleInterval
  • Background: colors and textures give a context for the environment
There is also a binding stack which changes the active node for NavInfo and Background.It is recommended to limit user movement through both the binding of various navigation types and the use of invisible walls and barriers to keep users from getting lost or sidetracked.



Existential Example: slow
Existential Example: speedy


When you go to the Columned Grove, clicking on the different objects will take you from Alice in Wonderland to Kubrick to Camus.

 

note: In order to efficiently acheive Einsteinian Relativity in simulation, we would really like to have the Timesensor cycleInterval field be an exposedField so scripts and interpolators can dynamically drive the world or clock time... maybe in X3D?
