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. Also available: X3D Scene Authoring Hints: Viewpoints and Navigation. |
