LocAR.js examples

  1. Hello World: Display a red cube just to the north of a fake GPS location. Can be tested on a desktop or laptop.
  2. GPS and Sensors: Requires a mobile device wih GPS and sensors. Demonstrates use of the GPS and the device sensors to show real AR. Gets your initial location and displays four coloured boxes to the north (red), south (yellow), west (blue) and east (green) of your initial location. Can be used as a test to check whether your device sensors are accurate; if the red box does not appear to the North, your device sensors may be mis-calibrated.
    3. +
  3. AR Objects: shows how you can add real AR objects with a given latitude and longitude and properties. Also shows how you can detect clicks on objects. Uses a hard-coded "fake" location and hard-coded objects, and you can rotate the three.js camera using the mouse, so will work on a desktop or laptop.

LocAR.js examples

  1. Hello World: Display a red cube just to the north of a fake GPS location. Can be tested on a desktop or laptop.
  2. GPS and Sensors: Requires a mobile device wih GPS and sensors. Demonstrates use of the GPS and the device sensors to show real AR. Gets your initial location and displays four coloured boxes to the north (red), south (yellow), west (blue) and east (green) of your initial location. Can be used as a test to check whether your device sensors are accurate; if the red box does not appear to the North, your device sensors may be mis-calibrated.
