locar-aframe.js

Location-based AR from AR.js - A-Frame components.

A-Frame components include:

• locar-webcam representing the webcam feed
• locar-camera representing a GPS-enabled camera
• locar-entity-place allowing entities to be positioned using latitude and longitude.

The latter two are more or less equivalent to the original AR.js gps-new-camera and gps-new-entity-place components but with some parameter changes.

locar-webcam

A-Frame component representing a webcam feed. Must be added to an A-Frame scene entity.

Parameters:

• idealWidth (number) - ideal webcam feed to use
• idealHeight (number) - ideal webcam height to use
• videoElement (string) - selector representing a video element to stream to, otherwise a video element is created.

locar-camera

A-Frame component representing a GPS-aware camera. Must be added to an A-Frame camera entity e.g. <a-camera> or <a-entity camera>

Parameters:

• simulateLatitude (number) - fake latitude to use
• simulateLongitude (number) - fake latitude to use
• simulateAltitude (number) - fake altitude to use
• positionMinAccuracy (number) - minimum accuracy in metres for GPS positions to be accepted.
• smoothingFactor (number) - smoothing factor for sensors, the same concept as in original AR.js.

locar-entity-place

A-Frame component representing an entity which can be added at a given latitude and longitude.

Parameters:

• latitude (number) - latitude of the entity
• longitude (number) - longitude of the entity
