Damper

The X3DDamperNode creates an IIR response that approaches the destination value according to the shape of the e-function only asymptotically but very quickly. An X3DDamperNode node is parameterized by the tau, order and tolerance fields

Filter: X3D only | Avalon only | All
id Name DataType PartType Default ValueType Description
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFBool enabled SFBool inputOutput TRUE Enables/disables the sensor node.
SFBool isActive SFBool outputOnly FALSE isActive true/false events are sent when the sensor gets active
SFFloat tolerance SFFloat inputOutput -1 [0, Inf) if tolerance is set to its default value -1, the browser implementation is allowed to find a good way for detecting the end of a transition. Browsers that do not have an elaborate algorithm can just use .001 as the tolerance value instead. If a value larger than zero is specified for tolerance, the browser shall calculate the difference between output and input for each internal filter being used and stop the animation only when all filters fall below that limit or are equal to it
SFInt32 order SFInt32 initializeOnly 1 [0, 5] The field order specifies the number of such internal filters. Specifying zero for order means that no filter is used. In this case the events received on set_destination are forwarded directly to output_changed
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFString description SFString inputOutput Text description to comment the sensor task. Can be used in run-time systems to give usefull feedback to the user and developer
SFString triggerName SFString initializeOnly Timer name of the dynamic context-slot which is used by the run-time environment (e.g. Jobs) to trigger the node. Life-Nodes will automatically connect the context-eventOutut to the triggerSlot-eventInput Slot.
SFTime tau SFTime inputOutput 0 [0, Inf) The field tau specifies the time-constant of the internal filters and thus the speed that the output of an X3DDamperNode responds to the input
SFTime triggerSlot SFTime inputOnly slot which is used internally to connect a dynamic context-slot which name is set by the triggerName value. Its used automatically to install run-time environment trigger.
