Three.js - issue with rendering - animation is shaking

I get a strange problem with the rendering of a sphere in rotation : the animation seems to shake and I don't know where this issue comes from.

Here's the example on this link

and the render function :

 function render() {

  controls.update();
  requestAnimationFrame(render);

  // For camera rotation : parametric parameter 
  timer = Date.now()*0.0001;

  // Coordinates of camera
  coordCamera.set(radiusCamera*Math.cos(timer), radiusCamera*Math.sin(timer), 0);

  // Rotate camera function
  rotateCamera();

  // Rendering
  renderer.render(scene, camera);

  }

with rotateCamera and computeRotation functions :

function computeRotation (objectRotation, coordObject) {

  // Apply rotation matrix 
  var rotationAll = new THREE.Matrix4();
  var rotationX = new THREE.Matrix4().makeRotationX(objectRotation.rotation.x);
  var rotationY = new THREE.Matrix4().makeRotationY(objectRotation.rotation.y);
  var rotationZ = new THREE.Matrix4().makeRotationZ(objectRotation.rotation.z);
  rotationAll.multiplyMatrices(rotationX, rotationY);
  rotationAll.multiply(rotationZ);

  // Compute world coordinates 
  coordObject.applyMatrix4(rotationAll);

  }

  function rotateCamera() {

  // Compute coordinates of camera
  computeRotation(torus, coordCamera);

  // Set camera position for motion
  camera.position.set(coordCamera.x, coordCamera.y, coordCamera.z)

  }

If someone could see what's wrong, this would be nice,

Thanks for your help

UPDATE :

I tried to insert the solution below of ; I didn't get to make work the animation, nothing is displayed : here my attempt on jsfiddle :

I tried also with performance.now() but animation is still shaking; you can check this on https://jsfiddle.net/ysis81/2Lok5agy/3/

I have started a bounty to resolve maybe this issue.

Solution

requestAnimationFrame will execute your callback render function with a timestamp parameter. Use that parameter to calculate how many milliseconds have passed since the last frame. Then use that diff as some percentage of rotation.

var mySpecificLogic = function (millesecondsSinceLastFrame) {
  // rotate your camera here
  // if you want it to rotate 20 degrees every second
  var rotPerSecond = 20;
  var rotationPerMS = rotPerSecond / 1000;
  var rotationInDegrees = millesecondsSinceLastFrame * rotationPerMS;
  // call your rotation function
  // note: if you are also trying to move the ball with the mouse
  //    you'll want a hook to disable this basic rotation

  // set the camera to whatever rotation you want

  renderer.render(scene, camera);
};


var startTheWholeThing = function() {
    var lastFrameTime;
    var deltaT;

    function recurse( thisFrameTime ) {
        window.requestAnimationFrame(recurse);
        lastFrameTime = lastFrameTime || thisFrameTime;
        deltaT = thisFrameTime - lastFrameTime;

        mySpecificLogic(deltaT);

        lastFrameTime = thisFrameTime;
    }
  recurse();
};

startTheWholeThing();
