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.
