Class ViewpointGroup

All Implemented Interfaces:
X3DChildNode, X3DNode, ViewpointGroup

public class ViewpointGroup extends X3DConcreteNode implements ViewpointGroup
ViewpointGroup can contain Viewpoint, OrthoViewpoint, GeoViewpoint and other ViewpointGroup nodes for better user-navigation support with a shared description on the viewpoint list.

X3D node tooltip: (X3D version 3.2 or later) [X3DChildNode] ViewpointGroup can contain Viewpoint, OrthoViewpoint, GeoViewpoint and other ViewpointGroup nodes for better user-navigation support with a shared description on the viewpoint list.
  • Hint: use ViewpointGroup as parent for Viewpoint, OrthoViewpoint, GeoViewpoint and other ViewpointGroup nodes to constrain location proximity where contained viewpoints are available to user.
  • Hint: ViewpointGroup and OrthoViewpoint require Navigation component level 3, which is higher than CADInterchange profile.
  • Hint: Viewpoint and ViewpointGroup descriptions together build simple menu/submenu lists for simple user navigation. ViewpointGroup is not an X3DGroupingNode, and can only contain a Metadata* node, Viewpoint, OrthoViewpoint, GeoViewpoint and other ViewpointGroup nodes.

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.
