ProximitySensor Visualization

Environmental sensors detect user visibility proximity and collision, while 3D spatial sound sources can greatly improve user engagement in a scene.

Event-producing environmental sensor nodes include LoadSensor, ProximitySensor, and VisibilitySensor. Audio nodes include Sound for aural spatialization and AudioClip for identifying sound files. MovieTexture nodes can also be used as an audio soundtrack source.

Relevant X3D Specification resources include the Environmental sensor component, Sound component and Texturing component.

Sound node coverage visualization

Authors can use a 10-step algorithm checklist (with example diagram) as an event-animation design pattern that helps build consistent event-routing chains. The supporting Chapter 7 slideset and course videos (NPS, YouTube) for X3D for Web Authors are available online via X3dGraphics.com.

The quick-reference sheet X3D Event Utility Nodes: Field Event Diagrams illustrates the functionality of the event utility nodes. These nodes receive and pass values that are sent via ROUTE connections.
