RICOH THETA S live 360º video stream rendering in Chrome via WebGL and a <video> texture

To get this working, you'll need the live-streaming software from RICOH. Install that and follow the live video instructions to connect your camera to your computer and have it show up as a video source.

If you're on a Mac, you can open up the FaceTime app and test it by picking "THETA UVC Blender" from the Video menu.

Once all of that is working, open up index.html and you should see the video rendered on the inside of a sphere that you can rotate around. Use the mouse to click and drag to move the camera around and the mouse wheel to zoom in and out.

navigator.mediaDevices.enumerateDevices().then((devices) => {
    // find the theta uvc blender device
    let theta = devices.find(device => device.label.match(/THETA UVC Blender/))
    return theta ? { optional: [{ sourceId: theta.deviceId }] } : true
  }).then((video) => {
    // get the camera
    return navigator.mediaDevices.getUserMedia({ video })
  }).then((stream) => {
    // create the video tag
    let video = document.body.appendChild(document.createElement('video'))
    video.src = window.URL.createObjectURL(stream)

// create a scene
    let scene = new THREE.Scene()

// attach the video to a texture
    let videoTexture = new THREE.Texture(video)
    videoTexture.minFilter = THREE.NearestFilter

// create a sphere at the origin textured on the inside by the video
    let sphere = new THREE.SphereGeometry(50, 16, 16),
        material = new THREE.MeshBasicMaterial({ map: videoTexture })
    material.side = THREE.BackSide
    scene.add(new THREE.Mesh(sphere, material))

// setup a light and camera inside the sphere
    let { width, height } = document.body.getBoundingClientRect()
    let light = new THREE.AmbientLight(0xFFFFFF),
        camera = new THREE.PerspectiveCamera(85, width / height, 1, 1000)

scene.add(light)
    scene.add(camera)

// controls for rotating around the origin
    let controls = new THREE.OrbitControls(camera)
    controls.autoRotate = true
    // invert rotation because we're inside the sphere
    controls.rotateSpeed = -1.0
    // camera needs to move off origin to see panning effect
    camera.position.z = 1

// render
    let renderer = new THREE.WebGLRenderer()
    renderer.setSize(width, height, true)
    document.body.appendChild(renderer.domElement)

;(function render() {
      requestAnimationFrame(render)

controls.update()

// update the video texture
      if (video.readyState === video.HAVE_ENOUGH_DATA)
        videoTexture.needsUpdate = true

renderer.render(scene, camera)
    })()
  }).catch((err) => {
    console.error(err)
  })
