Is it possible to dynamically add a 3D object to a three.js scene after it has been initialized and the user triggers a click event? How can this be achieved within the existing code structure provided?
You can find a prepared scene setup in this working example.
var camera, scene, renderer;
var geometry, material, mesh;
window.addEventListener("click", addCube, false);
function addCube() {
alert("Implement the code to add an object here!");
}
var init = function () {
renderer = new THREE.CanvasRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.z = 500;
scene = new THREE.Scene();
geometry = new THREE.CubeGeometry(200, 200, 200);
material = new THREE.MeshBasicMaterial({
color: 0x000000,
wireframe: true,
wireframeLinewidth: 2
});
mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
}
var animate = function () {
requestAnimationFrame(animate);
mesh.rotation.x = Date.now() * 0.0005;
mesh.rotation.y = Date.now() * 0.001;
renderer.render(scene, camera);
}
init();
animate();
