public class Group
extends X3DConcreteNode
implements Group

Group is a Grouping node that can contain most nodes.

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. Group node tooltip: [X3DGroupingNode,X3DVisibleObject] Group is a Grouping node that can contain most nodes.

• Hint: insert a Shape node before adding geometry or Appearance.

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.
