"Integrating a typeface.json font file into your three.js project: A step-by

I'm looking to incorporate 3D text into my website using the following code (reference: Labelling the vertices in AxisHelper of THREE.js):

var textGeo = new THREE.TextGeometry('Test', {
                size: 10,
                height: 5,
                curveSegments: 6,
                font: "helvetiker",
                style: "normal"});
var color = new THREE.Color();
color.setRGB(255, 250, 250);
var textMaterial = new THREE.MeshBasicMaterial({ color: color });
var text = new THREE.Mesh(textGeo , textMaterial);
scene.add(text);

To achieve this, it's necessary to include the font file helvetiker_regular.typeface.js before utilizing the text Geometry as Three.js relies on it for text geometry loading.

I've come across a json file named "helvetiker_regular.typeface.json" (https://github.com/mrdoob/three.js/tree/master/examples/fonts).

As a beginner in JS programming, I'm unsure how to properly include it to ensure my code functions correctly. Can someone provide guidance on this?

Answer №1

To load a font, you'll need to utilize a font loader:

const fontLoader = new THREE.FontLoader();
fontLoader.load("../path/to/font.json", function(tex){ 
    const textGeo = new THREE.TextGeometry('Example', {
            size: 10,
            height: 5,
            curveSegments: 6,
            font: tex,
    });
    const color = new THREE.Color();
    color.setRGB(255, 250, 250);
    const textMaterial = new THREE.MeshBasicMaterial({ color: color });
    const text = new THREE.Mesh(textGeo , textMaterial);
    scene.add(text);
})

If you only need to load the font once and don't need to save the texture for later use, the above code snippet will suffice. However, if you require the "tex" object to be accessible for future textgeometry objects, consider preloading it in your code.
