  • Figure 8.1. This example shows two TouchSensors, the door on the left is activated on a button-down (isActive true) event. The door on the right is opened on a button-up (touchTime) event.

  • Figure 8.2. This example (TouchSensor.x3d) shows the pump house, which is activated when the button is pressed down while the cursor is over the pump house.

  • Figure 8.3. A PlaneSensor is indicated by the red bar. The sensor output controls the amplitude of the pump.

    Figure 8.4. Shows how the diskAngle field determines whether a userís drag motion produces a rotation that is either in end-cap disk mode or cylinder-walls rotation mode.

  • Figure 8.5. The position of the CylinderSensor is indicated by the red knob and pointer. Rotating the knob changes the userís viewing angle.

    Figure 8.6. Setting a CylinderSensorís axis of rotation to be different from sensed geometry is best accomplished by using the design pattern shown in this scene graph.

  • Figure 8.7. The orientation NPS shark is manipulated with a SphereSensor on the blue sphere.

  • Figure 8.8. The KeySensor example allows the user to change the viewpoint.

  • Figure 8.9. A StringSensor allows the entry of the string "X3D: Extensible 3D Graphics!" into this X3D world.
