FaceLandmarker	src/web/FaceLandmarker.tsx

A @mediapipe/tasks-vision FaceLandmarker provider, as well as a useFaceLandmarker hook.

<FaceLandmarker>{/* ... */}</FaceLandmarker>

It will instanciate a FaceLandmarker object with the following defaults:

{
  basePath: "https://cdn.jsdelivr.net/npm/@mediapipe/[email protected]/wasm", // x.y.z will value the @mediapipe/tasks-vision version, eg: 0.10.2
  options: {
    baseOptions: {
      modelAssetPath: "https://storage.googleapis.com/mediapipe-models/face_landmarker/face_landmarker/float16/1/face_landmarker.task",
      delegate: "GPU",
    },
    runningMode: "VIDEO",
    outputFaceBlendshapes: true,
    outputFacialTransformationMatrixes: true,
  }
}

You can override defaults, like for example self-host tasks-vision's wasm/ and face_landmarker.task model in you public/ directory:

$ ln -s ../node_modules/@mediapipe/tasks-vision/wasm/ public/tasks-vision-wasm
$ curl https://storage.googleapis.com/mediapipe-models/face_landmarker/face_landmarker/float16/1/face_landmarker.task -o public/face_landmarker.task

import { FaceLandmarkerDefaults } from '@react-three/drei'

const visionBasePath = new URL("/tasks-vision-wasm", import.meta.url).toString()
const modelAssetPath = new URL("/face_landmarker.task", import.meta.url).toString()

const faceLandmarkerOptions = { ...FaceLandmarkerDefaults.options };
faceLandmarkerOptions.baseOptions.modelAssetPath = modelAssetPath;

<FaceLandmarker basePath={visionBasePath} options={faceLandmarkerOptions}>
