X3D Reference



LayoutLayer is a Grouping node that can contain most nodes. LayoutLayer content is clipped by the specified viewport node.

The LayoutLayer node belongs to the Layout component and its container field is layers. It is available since X3D version 3.2 or later.



SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFBool [in, out] isPickable TRUE

IsPickable determines whether pick traversal is performed for this layer.

SFNode [in, out] layout NULL [X3DLayoutNode]

The layout field contains an X3DLayoutNode node that provides the information required to locate and size the layout region of the LayoutGroup node relative to its parent’s layout region, and also to scale the contents of the LayoutGroup.

SFNode [in, out] viewport NULL [X3DViewportNode]

The content of the LayoutGroup is clipped by the specified viewport.

MFNode [in] addChildren

Input field addChildren.

MFNode [in] removeChildren

Input field removeChildren.

MFNode [in, out] children [ ] [X3DChildNode]

Grouping nodes contain a list of children nodes.


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.



  • Insert a Shape node before adding geometry or Appearance.


  • Better functional description needed in X3D specification.
