This project is a basic example of measuring real world objects using ARKit.
All the code is fully commented so the apps functionality should be clear to everyone.
Branches:
The Master Branch was originally compiled in XCode10 Beta using Swift 4.
An updated Branch called 'Swift4.2' contains the project built in XCode 10.5 Beta and uses Swift 4.2.
Requirements:
The project is setup for iPhone, and in Portait Orientation.
Core Functionality:
This project allows you to measure objects using touchGestures.
Each time the screen is tapped, a markerNode is placed, and the distances between these are calculated automatically using GLKit Math Utilities.
When there are more than 3 nodes on the screen, the angle between these is also calculated.
The SettingsMenu allows the user to toggle whether 3D Distance & Angle Labels should be shown, and whether markerNode placement should be done using either featurePoints or ARPlaneAnchors.
For more accurate results it is recommended the PlaneDetection be set to on.
Results are automatically displayed in: (a) Metres, (b) Centimetres, (c) Millimetres, (d) Feet, (e) Inches.
There is also a join function which can be used when more than 3 markers have placed.
Essentially this creates a shape, by joining the first and last markerNodes which have been placed.
