I have a simple THREE.js and I want to click on the round object, but when I click anywhere in the browser nothing happens. I followed this suggestion without success. The complete, full code is here:

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);

Please help me in finding out in what I have done wrongly. I am comparatively new to JavaScript also.
Another thing I wanted to add to the information above is that it works only with firefox and not chrome.
Thanks in advance.
I am trying to import my models from c4d into three.js.
I know there is a OBJLoader which works fine for me. If I want to use my exported wavefront (.obj) and convert it with convert_obj_three.py it doesn't return any errors and the json-file looks fine.
But if I want to load the generated .js-file in my three.js-script, it returns:
Uncaught SyntaxError: Unexpected token ;
This is what I've tried:
var loader2 = new THREE.JSONLoader();
loader2.load('assets/models/test.js', createScene);
function createScene(){
mesh = new THREE.Mesh();
scene.add(mesh);
}

I haven't been able to get my blender exported mesh to animate. Not even the included buffalo one that I can clearly see animated in the example. (which I've been trying to reproduce to no avail.
Here's the code, I suspect it's a really simple missing thing, but I have no idea. I doubt it's a blender issue since I haven't even been able to animate the included meshes.

The problem may be here:
var faceMaterial = new THREE.MeshFaceMaterial( materials );
faceMaterial.skinning = true;
The meshFaceMaterial is just like a container of other materials - it isn't itself a real material. Try iterating over its collection of materials:
var materials = faceMaterial.materials;
for (var i = 0,length = materials.length; i < length; i++) {
var material = materials[i];
material.skinning = true;
}
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!

ray.intersectObjects() is not recursive. You need to pass a list of the objects you want to test.
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:
