I have a cube in ThreeJS and I would like to rotate it 90 degrees clockwise every time I press a button. I think I have the basic gist of it: create a Three.Animation instance, bind it to the cube, and then have the animation begin every time I press the correct button. However, I'm having a difficult time understanding ThreeJS's API, because it doesn't seem to contain any examples for its methods.
This is THREE.js's Animation constructor: ( root, data, interpolationType, JITCompile ) I don't understand what goes into the fields. I'm guessing root would be where I put my cube, but what about the rest?
Also can I just call animation.play() to cause the animation whenever I want? And how does the animationHandler work?
I think for for rotating an object 90 degrees clockwise, using the TWEEN class will do. I think the Animation class is handy for heavier stuff (like bones/skin morphs/etc.)
To use the tween class there are 3 basic steps:
include the class in your file (<script src="js/Tween.js"></script>)
add your tween for the event you need (new TWEEN.Tween( cube.rotation ).to( { y:Math.random()}, 1000 ).easing( TWEEN.Easing.Quadratic.EaseOut).start();)
update the tween in your render loop (TWEEN.update();)
You can have a have a look at the cubes tween example for a start.
I've modified the default cube example to have the tween in:

I have a threejs project where I want to render a model and use the mouse to rotate around it.
this is the kind of idea
https://www.leroymerlin.fr/big2/guides-2021/experience-inspiration.html
I've got an example working, but the controls are bound by click and drags.
the goal is to render a model
have the ability of clicking on a button that will revolve the camera and render a new model as the old one dissipates (currently have a dropdown switching models)
on hovering over the model render a call to action/special mouse animation that would act as a link
be able to pan around the model using the mouse movement (not click drag).
-- I'm playing around with this demo first
https://threejs.org/examples/webgl_animation_keyframes.html
I tried adding stuff like here with the mouse
let mouseX = 0, mouseY = 0;
function onDocumentMouseMove( event ) {
mouseX = ( event.clientX - windowHalfX );
mouseY = ( event.clientY - windowHalfY );
}
function render() {
camera.position.x += ( mouseX - camera.position.x ) * 0.05;
camera.position.y += ( - mouseY - camera.position.y ) * 0.05;
camera.lookAt( scene.position );
renderer.render( scene, camera );
}
but it malfunctions causing the model to spin fast and zoom in too much.
Here is the latest code

When you do camera.position.x += mouseX - camera.position.x, you're using the x-position to set itself. These self-referencing values will give you erratic behavior. Try something simpler:
camera.position.x = mouseX * 0.05;
Or if you want a smooth animation, you could do linear-interpolation between 2 values:
let mouseXTarget = 0, mouseX = 0;
function onDocumentMouseMove( event ) {
mouseXTarget = ( event.clientX - windowHalfX ) * 0.05;
}
function render() {
// mouseX will smoothly try to reach its target
mouseX = THREE.MathUtils.lerp(mouseX, mouseXTarget, 0.1);
camera.position.x += mouseX;
camera.lookAt( scene.position );
}
I've created pointcloud with all points in an exact plane. I want the pointcloud to be highlighted and shown as a rectangle shape when the mouse is rolled over. For that, I think the pointcloud has to be converted in to a mesh, first.
I've googled for hours and tried to read thee.js documentation too. But couldn't find any solution. Could you please help me convert this pointcloud to a mesh. Thank you very much

Here is a quick and dirty modification of your sample, basically it creates a thin box with the same dimensions than your pointcloud and toggle its visibility when the mouse is getting over (using a raycaster). As far as I know there is no direct/built-in way to turn a pointcloud into a plane/mesh.

To reproduce this example you just need some random image and the THREE.js library. I do neither see any error in the console (related to this problem), nor any other console output during clicking on the browser...
I tried to add a method to one of the THREE.js objects as described in the documentation (geometry.addEventListener), but this also does not do anything.
document.addEventListener( 'click', onDocumentMouseDown, false);
I'm trying to implement this 3D model viewer, however I want to embed it into an already set div instead of making a new one as this does. So I've edited the code like so but it hasn't worked. Any help would be appreciated.

// This <div> will host the canvas for our scene.
container = document.getElementById( 'viewer' );
//document.body.appendChild( container );
// You can adjust the cameras distance and set the FOV to something
// different than 45°. The last two values set the clippling plane.
camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 2000 );
camera.position.z = 100;
// These variables set the camera behaviour and sensitivity.
controls = new THREE.TrackballControls( camera );
controls.rotateSpeed = 5.0;
controls.zoomSpeed = 5;
controls.panSpeed = 2;
controls.noZoom = false;
controls.noPan = false;
controls.staticMoving = true;
controls.dynamicDampingFactor = 0.3;
// This is the scene we will add all objects to.
scene = new THREE.Scene();
// You can set the color of the ambient light to any value.
// I have chose a completely white light because I want to paint
// all the shading into my texture. You propably want something darker.
var ambient = new THREE.AmbientLight( 0xffffff );
scene.add( ambient );
// Uncomment these lines to create a simple directional light.
// var directionalLight = new THREE.DirectionalLight( 0xffeedd );

var manager = new THREE.LoadingManager();
manager.onProgress = function ( item, loaded, total ) {
console.log( item, loaded, total );
};
var texture = new THREE.Texture();
var loader = new THREE.ImageLoader( manager );

loader.load( 'img/sickletexture.png', function ( image ) {
texture.image = image;
texture.needsUpdate = true;

// so that every pixel is crips and sharp. You can delete this lines
// if have a larger texture and want a smooth linear filter.
texture.magFilter = THREE.NearestFilter;
texture.minFilter = THREE.NearestMipMapLinearFilter;
} );

var loader = new THREE.OBJLoader( manager );
// As soon as the OBJ has been loaded this function looks for a mesh

var object = event;
object.traverse( function ( child ) {

} );
// My initial model was too small, so I scaled it upwards.
object.scale = new THREE.Vector3( 2, 2, 2 );

// centered in the view and leaves some space for overlay text.
object.position.y -= 2.5;
scene.add( object );
});

// append a canvas to our HTML page.
renderer = new THREE.WebGLRenderer();
renderer.setSize( document.getElementById('viewer').innerWidth, document.getElementById('viewer').innerHeight );
container.appendChild( renderer.domElement );
}
// The Loop
function animate() {
// This function calls itself on every frame. You can for example change
// the objects rotation on every call to create a turntable animation.
requestAnimationFrame( animate );

// and have it look exactly at the center of our scene.
controls.update();
camera.lookAt(scene.position);

I'm trying to get things to work myself and this code works for me with the latest version (66) of three. Its a little different to you example as I am using a vrml model rather than an obj and I handle the material differently. But it does run fine.

I found a rather easy solution, I'm surprised I did not find it earlier.
Create the 3D in a seperate html document (using the original script, not the edited one in the OP), then in the div <embed src="3d.html"></embed>
I'm using the OBJLoader to load a large 3D model (described in a .obj file) but it loads the whole file as a single Object3D object. Using scene.add(object) it adds the whole object to the scene.
I need to pick the selected mesh and change some of its properties, but when I add mouse function and use Ray.intersectObjects try to get the selected mesh it never works. I can not find where I made mistakes.
Would love some help with trying to get this working. Thanks!
