X3D Reference

ScalarDamper

ScalarDamper

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

The ScalarDamper node belongs to the Followers component and its container field is children. It is available since X3D version 3.3 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_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.

SFInt32 [ ] order 3 [0..5]

Order defines the number of internal filters (larger means smoother response, longer delay).

SFTime [in, out] tau 0.3 [0,∞)

Tau is the exponential-decay time constant for filter response in seconds.

SFFloat [in, out] tolerance -1 -1 or [0,∞)

-1 or [0,+∞) Absolute value for satisfactory completion proximity (-1 lets browser choose).

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.

Description

Hint

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