public class VisibilitySensorObject
extends X3DConcreteNode
implements VisibilitySensor

VisibilitySensor detects when user can see a specific object or region as they navigate the world.

X3D node tooltip: [X3DEnvironmentalSensorNode] VisibilitySensor detects when user can see a specific object or region as they navigate the world. The region sensed for visibility to the user is bounded by a rectangular box.

Hint: often used to attract user attention or improve performance.
Hint: this sensor detects user interactions affecting peer nodes and their child geometry.

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.
