What are the steps to utilizing three.js effectively?

I am currently working on a project that involves using three.js. I have been trying to learn the basics and wrote this simple code just to test it out. However, when I try to view it in the web browser, nothing appears.

Here is my code:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
    <script src="Three.js"></script>
</head>
<body>
    <script type="text/javascript">
        var renderer = new THREE.WebGLRenderer({ antialias: true });
        renderer.setSize(document.body.clientWidth,
                         document.body.clientHeight);

        document.body.appendChild(renderer.domElement);

        renderer.setClearColorHex(0xEEEEEE, 1.0);
        renderer.clear();

        // new THREE.PerspectiveCamera( FOV, viewAspectRatio, zNear, zFar );
        var camera = new THREE.PerspectiveCamera(45, width / height, 1, 10000);
        camera.position.z = 300;

        var scene = new THREE.Scene();
        var cube = new THREE.Mesh(new THREE.CubeGeometry(50, 50, 50),
                       new THREE.MeshBasicMaterial({ color: 0x000000 }));
        scene.add(cube);

        renderer.render(scene, camera);
    </script>
</body>
</html>

What could be causing it not to work? Any suggestions on what I might have done incorrectly?

Answer №1

Hello there! Can you please share with us the version of Three.js that you are currently using? It should display in the console upon loading if you are unsure. Also, could you let us know which browser you are utilizing for this project?

Just a quick side note, the use of renderer.setClearColorHex is now deprecated. The proper function to use is renderer.setClearColor.

Furthermore, I noticed that you set the camera dimensions with width / height, but it seems like these values are not defined anywhere in your code.

Lastly, consider adjusting the value for camera.position.z as setting it to 300 may be too far away to see a small cube at coordinates (0, 0, 0).

Please give these suggestions a try and inform us of the outcome. We are here to help!

Check out this demonstration.

You need to implement a main loop for continuous frame rendering. Additionally, as Darryl pointed out, what are the specified width and height parameters?
