X3D Reference

CoordinateInterpolator2D

CoordinateInterpolator2D

CoordinateInterpolator2D generates a series of SFVec2f or MFVec2f 2-tuple float values that can be ROUTEd to a SFVec2f or MFVec2f attribute.

The CoordinateInterpolator2D node belongs to the Interpolation 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.

SFFloat [in] set_fraction (-∞,∞)

Set_fraction selects input key for corresponding keyValue output.

MFFloat [in, out] key [ ] (-∞,∞)

Definition parameters for linear-interpolation function time intervals, in increasing order and corresponding to keyValues.

Hints

Number of keyValues must be an integer multiple of the number of keys! KeyValue/key integer multiple defines how many coordinates are sent in value_changed outputOnlys.

MFVec2f [in, out] keyValue [ ] (-∞,∞)

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

Hints

Number of keyValues must be an integer multiple of the number of keys! KeyValue/key integer multiple defines how many coordinates are sent in value_changed outputOnlys.

MFVec2f [out] value_changed

Linearly interpolated output value determined by current key time and corresponding keyValue pair.

Hint

KeyValue/key integer multiple defines how many coordinates are sent in value_changed outputOnlys.

Description

Hints

  • 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='3'/>
