ARCL Support

[intere]

Background

Adding / Testing ARCL (ARKit + CoreLocation) library to the example app for testing purposes.

Features Implemented

• Added a ViewController with an ARCL View and a MapView
  • ARCL View
    • Shows you the points you've tracked as a 1/2 meter red ball
    • Shows the starting and ending points as a vertical stack of tori (plural of torus)
    • Shows the in between points as an arrow, pointing towards the next point in the track
  • Map
    • Shows you the points you've tracked on a map as an annotation
  • Info Label
    • Shows your current horizontal / vertical accuracy
• Added a boolean property (showPoints) to the GeoTrackMap that will optionally show the individual points as annotations if set to true (false by default)
• Wired the ARView up to the MapViewController
• Added the ability to rename tracks in the track list.

User Experience

1. Create a track
2. Open the track (from the tracks tab)
3. Click on the "AR" button for the track
4. This loads the ARCL experience

• You should now be able to visualize the points as an array of tori or arrows (as explained in the features list above).
• Clicking on a point annotation on the map will do the following:
  • If the point you clicked on is represented as an arrow, the arrow will change from red to blue
  • The info area will tell you your distance (in meters) to the selected point
• The info area tells you:
  • Your current location services horizontal and vertical accuracy
  • The ARScene's current euler angles (think: euler angle of a camera that is the your screen, looking into the ARScene)
  • Heading of your current location
  • Heading accuracy (in degrees) of your current location
  • The current date / time

TODO

• Performance testing

Checklist

Screenshots

Updated prototype; first and last points are a vertical stack of 5 tori and the points in between are arrows that point to the next point:

Early prototype version - each point is a ball:
