Class PointPickSensor

java.lang.Object
All Implemented Interfaces:
X3DChildNode, X3DNode, X3DSensorNode, PointPickSensor, X3DPickSensorNode

public class PointPickSensor extends X3DConcreteNode implements PointPickSensor
PointPickSensor tests one or more pickingGeometry points in space as lying inside the provided pickTarget geometry.

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. PointPickSensor node tooltip: (X3D version 3.2 or later) [X3DPickSensorNode] PointPickSensor tests one or more pickingGeometry points in space as lying inside the provided pickTarget geometry. For each pickingGeometry PointSet coordinate point that lies inside the pickTarget geometry, a pickedPoint coordinate is returned along with a corresponding pickedGeometry node inside which the point lies.
  • Hint: because points represent an infinitely small location in space, sortOrder values CLOSEST and ALL_SORTED are defined to mean ANY and ALL respectively.
  • Hint: picking is performed between rendered frames of the event model. An author sets up the picking request in one frame by placing a LinePickSensor in the desired location. At the start of the next frame, any picking intersections are reported by the pick sensor.
  • Hint: picking notification is performed at the start of the frame for all enabled pick sensors once all other sensors are processed.
  • Hint: event timing details are explained in X3D Specification 4.4.8.3 Execution model https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS /Part01/concepts.html#ExecutionModel
  • Warning: order of contained nodes is significant, single pickingGeometry node must precede pickTarget node array.
  • Hint: PointSet can be used for pickingGeometry node.

Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
