Structure type:


VisibilitySensor detects when user can see a specific object or region as they navigate the world. This region is bounded by a box. Hint: often used to attract user attention or improve performance. Hint: Sensors are affected by peer nodes and children of peers.

id Name DataType PartType Default ValueType Description
SFFloat occlusionFactor_changed SFFloat outputOnly [0, 1] A raw estimation of the relative screensize. Does not account for real occlusions.
SFVec3f center SFVec3f inputOutput 0 0 0 Translation offset from origin of local coordinate system.
SFVec3f size SFVec3f inputOutput 0 0 0 size of visibility box, measured from center in meters.
SFTime enterTime SFTime outputOnly Time event generated when user's camera enters visibility region for sensor.
SFTime exitTime SFTime outputOnly Time event generated when user's camera exits visibility region for sensor.
SFString triggerName SFString initializeOnly Synchronize 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.
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
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
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.
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
