X3D Reference

Billboard

Billboard

Billboard is a Grouping node that can contain most nodes. Content faces the user, rotating about the specified axis. Set axisOfRotation=0 0 0 to fully face the user's camera.

The Billboard node belongs to the Navigation component and its container field is children. It is available since X3D version 3.0 or later.

Hierarchy

Fields

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.

SFVec3f [in, out] axisOfRotation 0 1 0 (-∞,∞)

AxisOfRotation direction is relative to local coordinate system.

Hint

Axis 0 0 0 always faces viewer.

SFVec3f [ ] bboxSize -1 -1 -1 [0,∞) or −1 −1 −1

Bounding box size is usually omitted, and can easily be calculated automatically by an X3D player at scene-loading time with minimal computational cost. Bounding box size can also be defined as an optional authoring hint that suggests an optimization or constraint.

Hint

Can be useful for collision computations or inverse-kinematics (IK) engines.

SFVec3f [ ] bboxCenter 0 0 0 (-∞,∞)

Bounding box center: optional hint for position offset from origin of local coordinate system.

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.

Hint

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.

Description

Hints

  • Put Billboard as close to the geometry as possible, nested inside Transform for local coordinate system.
  • Insert a Shape node before adding geometry or Appearance.

Warning

  • Don't put Viewpoint inside a Billboard.
