Class Scene


public class Scene
extends X3DConcreteStatement
Scene is the implicit root node of the X3D scene graph. This concrete class represents an X3D Scene statement.

X3D statement tooltip: [X3D statement] Scene is the root element that contains an X3D scene graph. Add nodes and children to build an X3D model. Only one Scene root element is allowed per X3D file.
  • Hint: Scene can contain regular children nodes, Metadata* nodes and LayerSet as top-level root nodes.
  • Hint: Scene is implicit, and not explicitly defined, in VRML97 and ClassicVRML encodings.
  • Hint: Scene nodes within Inline models report identical values as top-most root Scene node.
  • Warning: player support for attribute fields in this node is not defined.
  • Warning: Scene is a child of X3D statement, and must follow the (optional) head statement.
