Interface Switch

All Superinterfaces:
X3DBoundedObject, X3DChildNode, X3DGroupingNode, X3DNode
All Known Implementing Classes:
SwitchObject

public interface Switch
extends X3DGroupingNode
Switch is a Grouping node that only renders one (or zero) child at a time.

X3D node tooltip: [X3DGroupingNode] Switch is a Grouping node that only renders one (or zero) child at a time. Switch can contain most nodes. (Contained nodes are now called 'children' rather than 'choice', for consistent naming among all GroupingNodeType nodes.) All child choices continue to receive and send events regardless of whichChoice is active.
  • Hint: insert a Shape node before adding geometry or Appearance.
  • Hint: authors can temporarily hide test geometry under an unselected child of a Switch. This is a good alternative to "commenting out" nodes.
  • 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: 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: results are undefined if a bindable node (Background, Fog, NavigationInfo, OrthoViewpoint, TextureBackground, Viewpoint) is a contained descendant node of either LOD or Switch.
  • Hint: contained nodes must have type X3DChildNode, such as Group or Transform or Shape.
  • Warning: Switch is not allowed as parent of Appearance, Material, Color, Coordinate, Normal or Texture nodes.

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

  • Method Details

    • getBboxCenter

      float[] getBboxCenter()
      Provide array of 3-tuple float results from initializeOnly SFVec3f field named bboxCenter.

      Tooltip: Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.
      Specified by:
      getBboxCenter in interface X3DBoundedObject
      Specified by:
      getBboxCenter in interface X3DGroupingNode
      Returns:
      value of bboxCenter field
    • setBboxCenter

      Switch setBboxCenter​(float[] newValue)
      Accessor method to assign 3-tuple float array to initializeOnly SFVec3f field named bboxCenter.

      Tooltip: Bounding box center accompanies bboxSize and provides an optional hint for bounding box position offset from origin of local coordinate system.
      Specified by:
      setBboxCenter in interface X3DBoundedObject
      Specified by:
      setBboxCenter in interface X3DGroupingNode
      Parameters:
      newValue - is new value for the bboxCenter field.
      Returns:
      Switch - namely this same object to allow sequential method pipelining (i.e. consecutive method invocations on the same object).
    • getBboxSize

      float[] getBboxSize()
      Provide array of 3-tuple float results within allowed range of [0,infinity), or default value [-1 -1 -1], from initializeOnly SFVec3f field named bboxSize.

      Tooltip: Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.
      Specified by:
      getBboxSize in interface X3DBoundedObject
      Specified by:
      getBboxSize in interface X3DGroupingNode
      Returns:
      value of bboxSize field
    • setBboxSize

      Switch setBboxSize​(float[] newValue)
      Accessor method to assign 3-tuple float array to initializeOnly SFVec3f field named bboxSize.

      Tooltip: Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.

    • getChildren

      X3DNode[] getChildren()
      Provide array of X3DNode results (using an array consisting of properly typed nodes or ProtoInstanceObjects) from inputOutput MFNode field children.

      Tooltip: [X3DChildNode] Grouping nodes contain an ordered list of children nodes.
      • Hint: Each grouping node defines a coordinate space for its children, relative to the coordinate space of its parent node. Thus transformations accumulate down the scene graph hierarchy.
      • Hint: inputOnly MFNode addChildren field can append new X3DChildNode nodes via a ROUTE connection, duplicate input nodes (i.e. matching DEF, USE values) are ignored.
      • Hint: inputOnly MFNode removeChildren field can remove nodes from the children list, unrecognized input nodes (i.e. nonmatching DEF, USE values) are ignored.
      • Hint: X3D Architecture 10.2.1 Grouping and children node types, https://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/group.html#GroupingAndChildrenNodes
