Can Three.js be used to create a compact canvas?

I've successfully implemented a three.js scene on my website where users can drag to rotate an object. However, I don't want the scene to take up the entire webpage. I tried adjusting the field parameters with the following code:

renderer.setSize(400,400);

Despite these changes, users can still interact with the object by dragging anywhere on the webpage, making it difficult to select and copy text as usual. A perfect example of this issue is demonstrated on this website:

You'll notice the same problem occurs here - try copying the title and instead you'll end up rotating the ball slightly.

Any suggestions or solutions would be greatly appreciated. Thank you!

Answer №1

If you are utilizing TrackballControls, remember to specify the container element when constructing the TrackballControls object in order to capture mouse events for that specific element. Omitting this argument will result in capturing mouse events across the entire document.

For example:

// Identify the container element that will hold the canvas.
var container = document.getElementById("viewContainer");

// Append the canvas to the container element.
renderer = new THREE.WebGLRenderer({ alpha: true, antialias: true });
renderer.setSize(targetWidth, targetHeight);
renderer.setClearColor(0xededed, 0)
container.appendChild(renderer.domElement);

// Implement controls for panning, zooming, and rotating.
controls = new THREE.TrackballControls(camera, container);

Answer №2

If you want to customize a canvas element on your website, you can use CSS to adjust its attributes

and then assign it to the WebGLRenderer like this:

renderer = new THREE.WebGLRenderer({ alpha: true, antialias: true, canvas : document.getElementById('your canvas element id') });
