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. Viewpoint 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: <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.

Note that setting the DEF value clears the USE value.

Specified by:

setDEF in class X3DConcreteNode

Parameters:

newValue - is new value for the DEF field.

Returns:

Viewpoint - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

setDEF

public Viewpoint setDEF(SFString newValue)

Assign typed object value to SFString DEF field, similar to setDEF(String).

Parameters:

newValue - is new value for the DEF field.

Returns:

Viewpoint - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).

getUSE

public String getUSE()

Provide String value from inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Overrides:

getUSE in class X3DConcreteNode

Returns:

value of USE field

See Also:

• X3D Scene Authoring Hints: Naming Conventions

setUSE

public final Viewpoint setUSE(String newValue)

Accessor method to assign String value to inputOutput SFString field named USE.

Tooltip: USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).

• Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
• Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
• Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

Note: each USE node is still an independent object, with the USE value matching the DEF value in the preceding object.

Warning: invoking the setUSE() method on this node resets all other fields to their default values (except for containerField) and also releases all child nodes.

Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value.

Specified by:

setUSE in class X3DConcreteNode

Parameters:

newValue - is new value for the USE field.

Returns:

Viewpoint - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
