Creating a texture in Three.js using an image file

Having some difficulty with creating a texture from an image file using Three.js. Currently, attempting to create a mesh using the following function:

    var image = document.createElement('img');
    image.src = imageFile;
    var texture = new THREE.Texture(image);
    var mat = new THREE.MeshPhongMaterial();
    mat.map = texture;

    var mesh = new THREE.Mesh(new THREE.PlaneGeometry(20, 20), mat);
    var plane = mesh;
    plane.position.x = 0;
    scene.add(plane);

Encountering an issue where the texture renders black and the image does not display correctly.

If you want to easily turn an image into a texture, you can do so by loading it using the

THREE.ImageUtils.loadTexture(url, mapping, onLoad, onError)

method. Here's an example to demonstrate:

var mesh = new THREE.Mesh(
    new THREE.PlaneGeometry( 1, 1, 1, 1 ),
    new THREE.MeshBasicMaterial({ map: THREE.ImageUtils.loadTexture('/my-image.jpg') })
);

While the THREE.Texture constructor does allow you to use an image as the first parameter, it's important to ensure that the image has finished loading before using it. By utilizing ImageUtils, you can avoid the hassle of dealing with callbacks.
