  • Figure 12.1. Example configurations and uses of ProximitySensor: (a) a single ProximitySensor, (b) multiple independent ProximitySensors, and (c) a single ProximitySensor with multiple instances.

  • Figure 12.2. ProximitySensor reporting position and orientation in a Heads-Up Display (HUD), stabilizing HUD screen location.

  • Figure 12.3. Stereo-panning algorithm for attenuation of sound intensity is based on the azimuth angle relative to the userís current view direction.

  • Figure 12.4. Sound ellipsoids correspond to linear spatialization boundaries for attenuation of Sound node intensity.

  • Figure 12.5. Derivation and example values for an ellipse semiminor axis, given focus location and front/back distances. The upper plot shows intensity values corresponding to boundaries in the lower diagram.
  • Image Not Available - Figure 12-06
    Figure 12.6. Derivation of ellipsoid minHalfWidth and maxHalfWidth.

  • Figure 12.7. Boundary regions are shown for the Sound node. In this example, the outer region is an ellipsoid, and the inner region is a sphere.
