What is the best way to add clickable links to 3D objects and meshes with ThREE?

Question

What is the best way to add clickable links to 3D objects and meshes with ThREE?

My goal is to create a simple box that can act as a link when clicked. This seemingly straightforward task has proven difficult for me, so I would greatly appreciate any assistance. Despite my efforts to troubleshoot and research online, I have not been able to determine where I went wrong. While scouring Stack Overflow, I only found two similar questions, but they did not provide the answers I needed.

const coolTexture = new THREE.TextureLoader().load('cool.jpg');
const cool = new THREE.Mesh(
  new THREE.BoxGeometry(3, 3, 3),
  new THREE.MeshBasicMaterial({
    color: Math.random() * 0xffffff
  })
);

cool.userData = {
  URL: "http://stackoverflow.com"
};
scene.add(cool);

function linki() {
  if (intersects.length > 0) {
    window.open(intersects[0].object.userData.URL);
  }
}

document.body.onclick = linki

Answer №1

If you only have one box to work with, simply use window.open(object.URL); when the pointerdown event is triggered.

let scene, camera, renderer, cube;

window.addEventListener("pointerdown", () => {
  window.open(cube.URL);
});

//

function initialize() {
  // Initialization code
}

initialize();

body {
  font-family: sans-serif;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/0.145.0/three.min.js"></script>
<!DOCTYPE html>
<html>

<head>
    <title>Unique Title</title>
    <meta charset="UTF-8" />
</head>

<body>
    <div id="app"></div>

    <script src="src/index.js">
    </script>
</body>

</html>

However, if you are planning on creating multiple URLs, utilizing a Raycaster and checking which box was clicked would be more appropriate.

let scene, camera, renderer;
let objsToTest = [];

// Additional unique JavaScript code

init();

body {
  font-family: sans-serif;
}
