How to create a Sphere using three.js?

Question

I was making a sphere using three.js but the output is just a black screen as shown.

The code I used is:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>My first three.js app</title>
        <style>
            body { margin: 0; }
        </style>
    </head>
    <body>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r79/three.min.js"></script>
        <script>
            const scene = new THREE.Scene();
            const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );

            const renderer = new THREE.WebGLRenderer();
            renderer.setSize( window.innerWidth, window.innerHeight );
            document.body.appendChild( renderer.domElement );

            const geometry = new THREE.SphereGeometry( 15, 32, 16 );
            const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
            const sphere = new THREE.Mesh( geometry, material );
            scene.add( sphere );

            camera.position.z = 5;

            function animate() {
                requestAnimationFrame( animate );

                sphere.rotation.x += 0.01;
                sphere.rotation.y += 0.01;

                renderer.render( scene, camera );
            };

            animate();
        </script>
    </body>
</html>

I couldn't explain why the code was unable to render the sphere. What went wrong?

Thank you!

Your camera is inside the sphere. Move it a bit further away from the origin like in the following live example:

 const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000); camera.position.z = 50; const renderer = new THREE.WebGLRenderer(); renderer.setSize(window.innerWidth, window.innerHeight); document.body.appendChild(renderer.domElement); const geometry = new THREE.SphereGeometry(15, 32, 16); const material = new THREE.MeshBasicMaterial({ color: 0xffff00 }); const sphere = new THREE.Mesh(geometry, material); scene.add(sphere); function animate() { requestAnimationFrame(animate); sphere.rotation.x += 0.01; sphere.rotation.y += 0.01; renderer.render(scene, camera); }; animate();

 body { margin: 0; }
