I am excited to dive into learning three.js. After downloading the library from github: three.js
I attempted to run the first example of three.js as provided in the link above. However, I encountered a strange issue - the code runs perfectly fine on jsFiddle but does not work on my local machine.
Upon inspecting the console, I came across this error:
TypeError: document.body is null
[Break On This Error]
document.body.appendChild( renderer.domElement );
Check out the Live Working Demo on jsFiddle
Below is the exact code snippet that I copied from the provided link:
And yes, I have included the three.js library correctly on the page.
var camera, scene, renderer;
var geometry, material, mesh;
init();
animate();
function init() {
camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
camera.position.z = 1000;
scene = new THREE.Scene();
geometry = new THREE.CubeGeometry( 200, 200, 200 );
material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );
mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
renderer = new THREE.CanvasRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
}
function animate() {
// note: three.js includes requestAnimationFrame shim
requestAnimationFrame( animate );
mesh.rotation.x += 0.01;
mesh.rotation.y += 0.02;
renderer.render( scene, camera );
}
