Steps for incorporating Buttons into Three.Js interface

After implementing the code from the provided example webxr_ar_hittest, I successfully placed an object in my room. Now, I want to enable the ability to rotate the object with the press of a button. However, I haven't been able to find details on how to integrate UI and HUD elements alongside "webxr fullscreen" examples. Can someone offer guidance on how to display a DOM element above the rendered scene or include a rotation button within the scene? Are there any functionalities in three.js that could assist me with this situation?

Answer №1

A cutting-edge Web API has been developed to support this specific functionality, known as the WebXR DOM Overlays Module.

Based on information from the Chrome Status Platform, this feature is set to be automatically activated starting with Chrome 83.

I successfully tested one of the live demos related to this development using my Pixel:

The crucial section of code to implement this feature is highlighted below:

document.body.appendChild( ARButton.createButton( renderer, {
    optionalFeatures: [ 'dom-overlay', 'dom-overlay-for-handheld-ar' ],
    domOverlay: { root: document.body } } )
);

This showcases the updated method for creating the AR button.
