11. Enable Debugging Mode

For the debugging purpose, ARGear provides displaying AR information functions, which shows face landmark, face rect, and face axes. Debugging function can be enabled or disabled in real time.

By using setInferenceDebugOption function, you can set options for ARGSession. ARGInferenceDebugOption is defined in ARGSession.h.

<Definition. ARGInferenceDebugOption>
ARGSession.h
​
typedef NS_OPTIONS (NSInteger,ARGInferenceDebugOption)  {
   ARGInferenceOptionDebugNON               = 1 << 0,
   ARGInferenceOptionDebugFaceTracking      = 1 << 1,
   ARGInferenceOptionDebugFaceLandmark2D    = 1 << 2,
};

​

A sample code is written below.

// Sample Code. Enable and Disable Debugging Mode
​
ARGSession *argSession = [[ARGSession alloc] initWithARGConfig:argConfig error:&error];
…
 
// Enable Debugging Mode
[argSession setInferenceDebugOption:ARGInferenceOptionDebugFaceLandmark2D];
​
// Disable Debugging Mode
[argSession setInferenceDebugOption:ARGInferenceOptionDebugNON];

// Sample Code. Enable and Disable Debugging Mode
​
if let session = argSession {
​
    // Enable Debugging Mode
    session.inferenceDebugOption = .optionDebugFaceLandmark2D
    
    // Disable Debugging Mode
    session.inferenceDebugOption = .optionDebugNON
}
