Class LayerObject

java.lang.Object
All Implemented Interfaces:
X3DNode, Layer, X3DLayerNode, X3DPickableObject

public class LayerObject
extends X3DConcreteNode
implements Layer
Layer contains a list of children nodes that define the contents of the layer.

X3D node tooltip: (X3D version 3.2 or later) [X3DLayerNode] Layer contains a list of children nodes that define the contents of the layer.
  • Hint: no transformations are possible above each LayerSet/Layer combination in the scene graph hierarchy.
  • Hint: each Layer node contains its own binding stacks and thus has its own viewpoints and navigation.

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.

    • getObjectType

      public java.lang.String[] getObjectType()
      Provide array of String enumeration results with quoted value(s) ["ALL","NONE","TERRAIN",...] from inputOutput MFString field named objectType.

      Tooltip: The objectType field specifies a set of labels used in the picking process. Each string specified is treated as an independent label that needs to be matched against the same type in one of the pick sensor instances. Example: labeling a PickableGroup with the objectType value "WATER" and then attempting to intersect a pick sensor with objectType value "GROUND" fails since the objectType values do not match. Example: the special value "ALL" means that each node is available for picking regardless of the type specified by the pick sensor. Example: the special value "NONE" effectively disables all picking for this node and is the equivalent of setting the pickable field to false.
      • Hint: authors may define any value for objectType.
      • Hint: MFString arrays can have multiple values, so "separate each individual string" "by using quote marks".


      Available enumeration values for string comparison: ALL, NONE, TERRAIN.

      Hint: authors have option to choose from an extendible list of predefined enumeration values (ALL, NONE, TERRAIN).

      Tooltip: The objectType field specifies a set of labels used in the picking process. Each string specified is treated as an independent label that needs to be matched against the same type in one of the pick sensor instances.

      Assign a USE reference to another DEF node of same node type, similar to setUSE(String).

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