TransformSensor

TransformSensor generates output events when its targetObject enters, exits, and moves within a region in space (defined by a box).

The TransformSensor node belongs to the EnvironmentalSensor component and its container field is children. It is available since X3D version 3.2 or later.

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.

SFBool [in, out] enabled TRUE

Enables/disables node operation.

SFVec3f [in, out] size 0 0 0 [0,∞)

Size of intersection box, measured from center in meters.

SFVec3f [in, out] center 0 0 0 (-∞,∞)

Translation offset from origin of local coordinate system.

SFTime [out] enterTime

Time event generated when targetObject enters the box region for sensor.

SFTime [out] exitTime

Time event generated when targetObject exits the box region for sensor.

SFBool [out] isActive

IsActive true/false events are sent when triggering the sensor. isActive=true when targetObject enters the box region, isActive=false when targetObject exits the box region.

SFVec3f [out] position_changed

Sends translation event relative to center whenever the target object is contained within the box region and results change.

SFRotation [out] orientation_changed

Sends rotation event relative to center whenever the target object is contained within the box region and results change.

SFNode [in, out] targetObject NULL [X3DGroupingNode|X3DShapeNode]

TargetObject is the movable geometry represented by any valid X3DGroupingNode or X3DShapeNode which may enter or exit the box.

Description

Hints

Each TransformSensor node behaves independently of all other TransformSensor nodes, so that every enabled TransformSensor node affected by targetObject motion sends output events.
Multiply instanced (DEF/USE) TransformSensor nodes in different locations use the union of all boxes to check for enter and exit, detecting enter and exit for all instances of the box, and sending enter/exit events appropriately. For non-overlapping bounding boxes, position_changed and orientation_changed events are calculated relative to the coordinate system associated with the bounding box in which the proximity was detected.

Warnings

Results are undefined if boxes overlap for multiply instanced TransformSensor nodes.
A TransformSensor node with a zero-volume box (i.e. any size dimension equal to 0.0) cannot generate events, equivalent to enabled=false.
Unlike TouchSensor nodes, there is no notion of a TransformSensor node lower in the scene graph grabbing events.
