I'm interested in finding a way to animate text in ThreeJS that doesn't involve placing it directly on a plane. My ideal scenario would be to have the text appear as 2D, floating above a model. I've experimented with using divs positioned outside of the canvas, but encountered difficulty with proper alignment and responsiveness.
My goal is to achieve a visual effect similar to this, with the added animation of a line beneath the text.
If you're looking to incorporate a 2d canvas as a texture, consider the following approach:
const canvas = document.createElement('canvas');
const context = canvas.getContext('2d');
context.font = "Bold 40px Arial";
context.fillStyle = "rgba(255,0,0,0.95)";
context.fillText('Hello, world!', 0, 50);
// Assign canvas contents as a texture
const texture = new THREE.Texture(canvas);
texture.needsUpdate = true;
const material = new THREE.MeshBasicMaterial({ map: texture, side: THREE.DoubleSide });
material.transparent = true;
const mesh = new THREE.Mesh(
new THREE.PlaneGeometry(canvas.width, canvas.height),
material
);
