How to rotate orientation?


How to rotate orientation?

I wish this helpful for you What I understand from your question is that you want to force one view controller to always appear in landscape mode.
Here is how to do it in Swift 3. Add this code to the view controller that you want to appear in landscape:
code :
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {  
    return UIInterfaceOrientationMask.landscape  
}  

override var shouldAutorotate: Bool {  
    return false  
}

This might help you EDIT 3: It just occurred to me that the solution below, while correct, is unnecessarily complicated. You can achieve the same effect by simply multiplying the rotation matrix by the orientation matrix to compute the new orientation:
code :
M = R * M
M = [1  0  0  0]
    [0  1  0  0]
    [0  0  1  0]
    [0  0  0  1]
M = [Ux Vx Wx 0]
    [Uy Vy Wy 0]
    [Uz Vz Wz 0]
    [0  0  0  1]
U = [1]  V = [0]  W = [0]
    [0]      [1]      [0]
    [0]      [0]      [1]
U = [0]  V = [-1]  W = [0]
    [1]      [ 0]      [0]
    [0]      [ 0]      [1]
M = [0 -1  0  0]
    [1  0  0  0]
    [0  0  1  0]
    [0  0  0  1]
U = [0  ]  V = [-1]  W = [ 0  ]
    [0.7]      [ 0]      [-0.7]
    [0.7]      [ 0]      [ 0.7]
M = [0    -1   0    0]
    [0.7   0  -0.7  0]
    [0.7   0   0.7  0]
    [0     0   0    1]
Yaw(90)*Pitch(45) = [0 -1 0 0]*[1  0    0    0] = [0  -0.7  0.7  0]
                    [1  0 0 0] [0  0.7 -0.7  0]   [1   0    0    0]
                    [0  0 1 0] [0  0.7  0.7  0]   [0   0.7  0.7  0]
                    [0  0 0 1] [0  0    0    1]   [0   0    0    1]

Pitch(45)*Yaw(90) = [1  0    0    0]*[0 -1 0 0] = [0    -1   0    0]
                    [0  0.7 -0.7  0] [1  0 0 0]   [0.7   0  -0.7  0]
                    [0  0.7  0.7  0] [0  0 1 0]   [0.7   0   0.7  0]
                    [0  0    0    1] [0  0 0 1]   [0     0   0    1]

Any of those help Why don't you do the following (done this way by most developers) Create a Portrait and Landscape layout in a DataTemplate Bind the Content in the page to a DataTemplate in the Page/ViewModel When the Orientation changes then update the DataTemplate DP/INotify to the correct one
This will probably be the easiest option

Three JS rotate group with same orientation as camera for View Cube/Orientation Cube

seems to work fine First of all in view space, the X-axis points to the right, the Y-axis points is up and the Z-axis points out of the canvas.
So you have to choose an initial position for the OrientationHelper camera on the positive Z-axis:
code :
class OrientationHelper {
    constructor(canvas) {
        // [...]

        this.camera = new THREE.PerspectiveCamera(75, size / size, 0.1, 1000);
        this.camera.position.set(0, 0, 2);

        // [...]
class OrientationHelper {
    // [...]

    setCameraRotation(rotation) {
        this.group.setRotationFromMatrix(rotation);
    }

    // [...]
let rotMat = new THREE.Matrix4().makeRotationFromEuler(camera.rotation);
let invRotMat = new THREE.Matrix4().getInverse(rotMat); 

orientationHelper.setCameraRotation(invRotMat);
orientationHelper.update();
class OrientationHelper {
  constructor(canvas) {
    this.canvas = canvas;
    
    this.ref = [
      [new THREE.Vector3(1,0,0), 0xFF0000],
      [new THREE.Vector3(0,1,0), 0x00FF00],
      [new THREE.Vector3(0,0,1), 0x0000FF],
    ]

    var size = 200;
    this.scene = new THREE.Scene();
    this.camera = new THREE.PerspectiveCamera(75, size / size, 0.1, 1000);
    this.camera.position.set(0, 0, 2);

    this.renderer = new THREE.WebGLRenderer({alpha: true});
    this.renderer.setSize(size, size);
    canvas.appendChild(this.renderer.domElement);
    
    var controls = new THREE.OrbitControls(this.camera, this.renderer.domElement);
    
    var geometry = new THREE.SphereGeometry( .1, 32, 32 );
    var material = new THREE.MeshBasicMaterial( {color: 0xffffff} );
    var sphere = new THREE.Mesh( geometry, material );
    this.scene.add( sphere );

    this.group = new THREE.Group();
    for(var pos of this.ref) {
      var geometry = new THREE.BoxGeometry(.25,.25,.25);
      var material = new THREE.MeshBasicMaterial({
        color: pos[1]
      });
      var cube = new THREE.Mesh(geometry, material);
      cube.position.copy(pos[0]);
      this.group.add(cube);
    }

    this.scene.add(this.group);
  }

  setCameraRotation(rotation) {
    this.group.setRotationFromMatrix(rotation);
  }
  
  update() {
  	this.renderer.render(this.scene, this.camera);
  }
}

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

var controls = new THREE.OrbitControls(camera, renderer.domElement);
camera.position.set(0, 3, 3);
controls.update();

//controls.autoRotate = true;

var size = 10;
var divisions = 10;

var gridHelper = new THREE.GridHelper(size, divisions);
scene.add(gridHelper);

var axesHelper = new THREE.AxesHelper(5);
scene.add(axesHelper);

 // material
  var material = new THREE.MeshBasicMaterial({
    color: 0xffffff,
    vertexColors: THREE.FaceColors
  });

var geometry = new THREE.BoxGeometry();

 // colors
  red = new THREE.Color(1, 0, 0);
  green = new THREE.Color(0, 1, 0);
  blue = new THREE.Color(0, 0, 1);
  var colors = [red, green, blue];
  
  for (var i = 0; i < 3; i++) {
    geometry.faces[4 * i].color = colors[i];
    geometry.faces[4 * i + 1].color = colors[i];
    geometry.faces[4 * i + 2].color = colors[i];
    geometry.faces[4 * i + 3].color = colors[i];
  }
  
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// Orientation
var orientationHelper = new OrientationHelper(document.getElementById("orientation-helper"));

function animate() {
  requestAnimationFrame(animate);
  controls.update();

  let rotMat = new THREE.Matrix4().makeRotationFromEuler(camera.rotation);
  let invRotMat = new THREE.Matrix4().getInverse(rotMat); 
  orientationHelper.setCameraRotation(invRotMat);
	orientationHelper.update();
  
  renderer.render(scene, camera);
}

animate();

This might help you There's probably enough information in the other answers and comments to put this all together, but here's a working code example.
This extension method will take a System.Drawing Image, read its Exif Orientation tag (if present), and flip/rotate it (if necessary).

I wish this help you My program processes some images in batch.I currently need to read the exif orientation tag of the image,rotate it to proper orientation,do some processing and save the image without any EXIF Orientation Tag,but with proper Rotation.(or with EXIF tag with Proper Orientation)
