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.

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.

Warning

Number of keys must match number of keyValues!

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

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

Warning

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.

Description

Hints

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'/>
