GeoPositionInterpolator

GeoPositionInterpolator animates objects within a geographic coordinate system. GeoPositionInterpolator can contain a GeoOrigin node. Typical input: ROUTE someTimeSensor.fraction_changed TO someInterpolator.set_fraction Typical output: ROUTE someInterpolator.value_changed TO destinationNode.set_attribute.

id Name DataType PartType Default ValueType Description
SFBool enabled SFBool inputOutput TRUE Flag to enable/disable the node behaviour
SFNode geoOrigin SFNode initializeOnly GeoOrigin The geoOrigin field is used to specify a local coordinate frame for extended precision.
MFString geoSystem MFString initializeOnly 'GD','WE' Defines the geographic coordinate system that will be used for the geospatial coordinates in that node.
SFVec3d geovalue_changed SFVec3d outputOnly (-inf, inf) corresponds to value_changed, but positions are specified in the geographic system given by geoSystem.
MFFloat key MFFloat inputOutput Definition parameters for linear-interpolation function time intervals, in increasing order and corresponding to keyValues. Hint: number of keys must match number of keyValues!
MFVec3d keyValue MFVec3d initializeOnly Output values for linear interopolation, each corresponding to time-fraction keys. Hint: number of keys must match number of keyValues!
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
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFFloat set_fraction SFFloat inputOnly set_fraction selects input key for corresponding keyValue output.
SFVec3f value_changed SFVec3f outputOnly Linearly interpolated output value determined by current key time and corresponding keyValue pair.
