Class NavigationInfo

java.lang.Object
org.web3d.x3d.jsail.X3DConcreteElement
org.web3d.x3d.jsail.X3DConcreteNode
org.web3d.x3d.jsail.Navigation.NavigationInfo
All Implemented Interfaces:
X3DBindableNode, X3DChildNode, X3DNode, NavigationInfo
public class NavigationInfo extends X3DConcreteNode implements NavigationInfo
NavigationInfo describes the user's viewing model, user navigation-interaction modalities, and also dimensional characteristics of the user's (typically invisible) avatar.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. NavigationInfo node tooltip: [X3DBindableNode] NavigationInfo describes the user's viewing model, user navigation-interaction modalities, and also dimensional characteristics of the user's (typically invisible) avatar.
  • Hint: for inspection of simple objects, usability often improves with type="EXAMINE" "ANY"
  • Hint: Background, Fog, GeoViewpoint, NavigationInfo, OrthoViewpoint, TextureBackground and Viewpoint are bindable nodes, meaning that no more than one of each node type can be active at a given time.
  • Hint: NavigationInfo types '"WALK" "FLY"' support camera-to-object collision detection.
  • Warning: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint, TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch. Avoid this authoring pattern.
  • Hint: Regardless of viewpoint jump value at bind time, the relative viewing transformation between user's view and defined position/orientation is stored for later use when un-jumping (returning to the viewpoint when subsequent viewpoint is unbound).
  • Hint: customizable design pattern for dedicated Viewpoint/NavigationInfo pair: <Viewpoint DEF='SpecialView'/> <NavigationInfo DEF='SpecialNav'/> <ROUTE fromNode='SpecialView' fromField='isBound' toNode='SpecialNav' toField='set_bind'/>
  • Hint: X3D Scene Authoring Hints, Viewpoints https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Viewpoints

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
