VisibilitySensor

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.
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.
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
