Interface VisibilitySensor

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

public interface VisibilitySensor
extends X3DEnvironmentalSensorNode
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 interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
