X3D Reference



ViewpointGroup collects Viewpoint, OrthoViewpoint and other ViewpointGroup nodes for better user-navigation support with a shared description on the viewpoint list.

The ViewpointGroup node belongs to the Navigation component and its container field is children. 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] displayed TRUE

Displayed determines whether this ViewpointGroup is displayed in the current viewpoint list.

SFString [in, out] description ""

Text description or navigation hint to identify this ViewpointGroup.


Use spaces, make descriptions clear and readable. Many XML tools substitute XML character references automatically if needed (such as & for & ampersand, or " for " quotation mark).


Without description, this ViewpointGroup is unlikely to appear on browser Viewpoints menu.

SFBool [in, out] retainUserOffsets FALSE

Retain (true) or reset to zero (false) any prior user navigation offsets from defined viewpoint position, orientation.

SFVec3f [in, out] size 0 0 0 (-∞,∞)

Size of proximity box around center location within which ViewpointGroup is usable and displayed on viewpoint list.


Size 0 0 0 specifies that ViewpointGroup is always usable and displayable.

SFVec3f [in, out] center 0 0 0 (-∞,∞)

Center specifies center point of proximity box within which ViewpointGroup is usable and displayed on viewpoint list.

MFNode [in, out] children [ ] [X3DViewpointNode | ViewpointGroup]

Input/Output field children.



  • Use ViewpointGroup as parent for Viewpoint and OrthoViewpoint to constrain location proximity where contained viewpoints are available to user.
  • ViewpointGroup and OrthoViewpoint require Navigation component level 3, which is higher than CADInterchange profile.
  • Viewpoint and ViewpointGroup descriptions together build simple menu/submenu lists for simple user navigation.
