Class Viewpoint

All Implemented Interfaces:
X3DBindableNode, X3DChildNode, X3DNode, Viewpoint, X3DViewpointNode

public class Viewpoint extends X3DConcreteNode implements Viewpoint
Viewpoint provides a specific location and direction where the user may view the scene.

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. X3D node tooltip: [X3DViewpointNode] Viewpoint provides a specific location and direction where the user may view the scene. Viewpoints are the primary way for a user to navigate within a scene, and for an author to show critical aspects of a model. Hint: a sequence of good Viewpoints with understandable descriptions can provide a guided tour of a model. Hint: the currently bound NavigationInfo node has a major effect on how a user might change viewing position and orientation after reaching this Viewpoint. Hint: consider paired Viewpoint/NavigationInfo node combinations by defining ROUTE connections between corresponding isBound/set_bind fields. Hint: consider how users might interact with the current X3D model, either standalone or as an Inline within a larger parent scene. 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: GeoViewpoint OrthoViewpoint and Viewpoint share the same binding stack, so no more than one of these nodes can be bound and active at a given time. 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. Warning: do not include GeoViewpoint OrthoViewpoint or Viewpoint as a child of LOD or Switch, instead use ViewpointGroup as parent to constrain location proximity where the viewpoint is available to user. 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: &lt;Viewpoint DEF='SpecialView'/&gt; &lt;NavigationInfo DEF='SpecialNav'/&gt; &lt;ROUTE fromNode='SpecialView' fromField='isBound' toNode='SpecialNav' toField='set_bind'/&gt; Hint: X3D Scene Authoring Hints, Viewpoints <a href="https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Viewpoints" target="_blank">https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Viewpoints</a> *


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.
