X3D Reference



SquadOrientationInterpolator performs non-linear interpolation among paired lists of rotation values to produce an SFRotation value_changed output event.

The SquadOrientationInterpolator node belongs to the Interpolation 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.

SFFloat [in] set_fraction (-∞,∞)

Set_fraction selects input key for corresponding use of keyValue, keyVelocity values for output computation.

SFBool [in, out] closed FALSE

Input/Output field closed.

MFFloat [in, out] key [ ] (-∞,∞)

Definition parameters for nonlinear-interpolation function time intervals, in increasing order and corresponding to keyValue, keyVelocity array values.


Number of keys must match number of keyValues!

MFRotation [in, out] keyValue [ ] (-∞,∞)

Output values for nonlinear interpolation, each corresponding to time-fraction keys.


Number of keys must match number of keyValues!

SFRotation [out] value_changed

Nonlinearly interpolated output value computed by using current time fraction along with corresponding key, keyValue and keyVelocity values.



  • Squad is an acronym for Spherical Cubic Interpolation.
  • Typical input connection is ROUTE someTimeSensorDEF.fraction_changed TO thisInterpolatorDEF.set_fraction
  • Typical output connection is ROUTE thisInterpolatorDEF.value_changed TO someDestinationNodeDEF.set_someAttribute.
  • Include <component name='Interpolation' level='5'/>
