This is a set of utility functions which can be used to decipher CLM Trackr
You can consume these utility functions in the following two ways:
var utils = ;utilsfaceOrientationutilsgetFaceSizeutilstextureCaptureutilsforeheadutilshalo
var faceOrientation = ;var getFaceSize = ;var textureCapture = ;var forehead = ;var halo = ;
Here are examples as to how to use these utility functions:
var faceOrientation = ;var getFaceSize = ;var textureCapture = ;var forehead = ;var halo = ;// clmPositions would be the positions of vertices from clm// returns aproximated y and z rotations of face in degreesvar rotationDegrees = ;console; // z rotation of faceconsole; // y rotation of face// an object containing 2d width and height of face is returnedvar size = ;console; // width of faceconsole; // height of face// add 10 points to create an approximate forehead (original array is modified) since the CLM positions do not include one;// create a halo (original array is modified) if you want extra padding around the face;// textureCapture returns UV coordinates based on the clmPositions and can optionally extract a texture from the image or video element onto a canvas2d context.var texOptions =outContext: null //an optional canvas2d context if you want a texture rendered from options.image or options.videooptionsvideo: null //an optional video element that was used to generate the CLM pointsoptionsimage: null //an optional image element that was used to generate the CLM pointsoptionsforehead: false //include or exclude the points that make up the foreheadoptionshalo: false //include or exclude the points that make up the halo;var uvs = ;
