            Extract yaw/pitch/roll from faceAnchor in ARKit
            Asked 2021-Apr-28 at 09:41

            Using ARKit for facetracking, I get faceAnchor (ARFaceAnchor) as soon as the face is detected, which provides a simd_float4x4 matrix. I know about transformation matrices, and am also aware that the topic has been partially addressed (here: How to get values from simd_float4 in objective-c , and here: simd_float4x4 Columns), but is there a straighforward way to get yaw/pitch/rool values from the face anchor? (in order to feed my y/p/r values in the code below).

            As there is apparently not (yet) a function provided by Apple for that purpose, it is a priori required to implement quaternion to euler angles computation. With these mathematical resources, and a radian-to-degrees conversion function, this can be implemented as an extension, as follows:

            How can I encode an array of simd_float4x4 elements in Swift (convert simd_float4x4 to Data)?
            Asked 2020-Aug-31 at 02:35

            I am building an app that captures facetracking data from the iPhone TrueDepth camera.

            I need to write this data to files so I can use it as the basis for another app.

            Within the app, the data is saved into four separate arrays, one containing ARFaceGeometry objects, and the other three with transform coordinates as simd_float4x4 matrices.

            I am converting the arrays into Data objects using archivedData(withRootObject: requiringSecureCoding:) then calling write(to:) on them to create the files.

            The file containing the ARFaceGeometry data is written and read back in correctly. But the three simd_float4x4 arrays aren't being written, even though the code for doing so is identical. Along with my print logs, the error being given is 'unrecognized selector sent to instance'.

            Can't get FaceTracker class to work on HoloLens 2
            Asked 2020-Jul-14 at 11:23

            I'm having trouble getting the FaceTracker Class to work on HoloLens 2. As soon as I try to detect the faces with ProcessNextFrameAsync Method I get an exception of the following kind:

            System.Runtime.InteropServices.COMException (0x80004005): Unspecified error

            This is only the first part of the error message, if more information is needed, I can add that.

            This is an official sample show how to use the FaceTracker class to find human faces within a video stream: Basic face tracking sample. And in line 256, that is the main point to get a preview frame from the capture device.

            However, base on your code, you have created a VideoFrame object and specified the properties and format to it, but you are missing invoke GetPreviewFrameAsync to convert the native webcam frame into the VideoFrame object.

            You can try the following code to fix it:

            2D face tracking on Spark AR
            Asked 2020-Jul-07 at 22:17

            I've been trying to make the face texture in a 2D canvas/plane move only along the X/Y axis, following the movements of the face without rotating, with the 2D background camera texture reflected accurately on top. Right now, when I connect the canvas to the face tracker I'm getting distorted scale, and the 2D plane rotates in 3D space. See below for the current canvas/camera texture/face tracker set-up. Manual scaling results in poor tracking.

            Here is my code:
