Interface GeoViewpoint

All Superinterfaces:

All Known Implementing Classes:
GeoViewpoint

public interface GeoViewpoint extends X3DViewpointNode
GeoViewpoint specifies viewpoints using geographic coordinates.

X3D node tooltip: [X3DViewpointNode] GeoViewpoint specifies viewpoints using geographic coordinates. GeoViewpoint can contain a GeoOrigin node. Since GeoViewpoint must navigate smoothly inside a curved geographic coordinate system, it includes both Viewpoint and NavigationInfo attributes.
  • Hint: alternatively can use GeoLocation or GeoTransform as parent of a Viewpoint node to orient geospatial views.
  • Hint: include <component name='Geospatial' level='1'/>
  • Hint: when a GeoViewpoint node is bound, it also overrides the currently bound NavigationInfo node in the scene and controls user navigation for smoother geospatial interaction.
  • 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.
  • Warning: GeoViewpoint navType and headlight fields were removed as part of X3D version 3.3, authors can instead use a NavigationInfo node for those fields in prior X3D versions 3.0, 3.1 or 3.2. Upgrading such legacy scenes to version 3.3 or greater is preferred and recommended.
  • 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'/>
  • Warning: avoid having GeoLocation or GeoTransform as a parent or ancestor node of GeoViewpoint, since multiple geospatial transformations then occur with unpredictable results.
  • Hint: X3D Scene Authoring Hints, Viewpoints https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Viewpoints

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
