X3D Example Archives: X3D4WA, X3D for Web Authors, Chapter 04 Viewing Navigation

Anchor bookmarked-Viewpoint comparison, view from front

Authors can design scenes to help users navigate to Viewpoints of interest, and also create user-selectable geometry links using an Anchor (just like HTML).

Viewpoint nodes are the primary means for users to explore a scene. NavigationInfo nodes enable different user-interaction styles (FLY, WALK, EXAMINE etc.) as appropriate. Only one Viewpoint and one NavigationInfo node can each be active a time, with order of selection controlled via a binding stack.

The supporting Chapter 4 slideset and course videos (NPS, YouTube) for X3D for Web Authors are available online via X3dGraphics.com.

   BindingOperations Binding Operations Illustrate Viewpoint binding operations (in gory detail!) as described in Chapter 4 concepts. Scene design: a TimeSensor clock drives and IntegerSequencer for each t0/t1/etc. event, and a customized Script node sends bind/unbind events to the correct Viewpoint. Display the browser console to see occurrence of each event.
