For me this function works (Three.js version 69):

function createVector(x, y, z, camera, width, height) {
        var p = new THREE.Vector3(x, y, z);
        var vector = p.project(camera);

        vector.x = (vector.x + 1) / 2 * width;
        vector.y = -(vector.y - 1) / 2 * height;

        return vector;
    }
