X3D Reference



ScalarChaser generates a series of single floating-point values that progressively change from initial value to destination value.

The ScalarChaser node belongs to the Followers 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_value

Set_value resets current value of this node.

SFFloat [in] set_destination

Set_destination resets destination value of this node.

SFFloat [ ] initialValue

Initial starting value for this node.

SFFloat [ ] initialDestination

Initial destination value for this node.

SFTime [ ] duration 1 [0,∞)

Duration is the time interval for filter response in seconds.

SFBool [out] isActive

IsActive true/false events are sent when follower-node computation starts/stops.

SFFloat [out] value_changed

Computed output value that approaches within tolerance of destination value, as determined by elapsed time, order and tau.



  • Value_changed output events can be ROUTEd to an interpolator node's set_fraction field, for example.
