Interface TransformSensor

All Superinterfaces:
X3DChildNode, X3DEnvironmentalSensorNode, X3DNode, X3DSensorNode
All Known Implementing Classes:
TransformSensor

public interface TransformSensor extends X3DEnvironmentalSensorNode
TransformSensor generates output events when its targetObject enters, exits, and moves within a region in space (defined by a box).

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. X3D node tooltip: (X3D version 3.2 or later) [X3DEnvironmentalSensorNode] TransformSensor generates output events when its targetObject enters, exits, and moves within a region in space (defined by a box). Hint: Each TransformSensor node behaves independently of all other TransformSensor nodes, so that every enabled TransformSensor node affected by targetObject motion sends output events. Hint: 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. Warning: results are undefined if boxes overlap for multiply instanced TransformSensor nodes. Warning: a TransformSensor node with a zero-volume box (i.e. any size dimension equal to 0.0) cannot generate events, equivalent to enabled=false. Warning: unlike TouchSensor nodes, there is no notion of a TransformSensor node lower in the scene graph grabbing events. *


Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
