There are often times when you might need to use text in your three.js application - here are a couple of ways that you can do so.
Using HTML is generally the easiest and fastest manner to add text. This is the method used for descriptive overlays in most three.js examples.
You can add content to a
<div id="info">Description</div>
and use CSS markup to position absolutely at a position above all others with a z-index especially if you are running three.js full screen.
#info {
position: absolute;
top: 10px;
width: 100%;
text-align: center;
z-index: 100;
display:block;
}
Use these renderers to draw high-quality text contained in DOM elements to your three.js scene. This is similar to 1. except that with these renderers elements can be integrated more tightly and dynamically into the scene.
Use this method if you wish to draw text easily on a plane in your three.js scene.
Use this method if you prefer working with your 3d applications and importing the models to three.js.
If you prefer to work purely in THREE.js or to create procedural and dynamic 3D text geometries, you can create a mesh whose geometry is an instance of THREE.TextGeometry:
new THREE.TextGeometry( text, parameters );
In order for this to work, however, your TextGeometry will need an instance of THREE.Font to be set on its "font" parameter. See the [page:TextGeometry] page for more info on how this can be done, descriptions of each accepted parameter, and a list of the JSON fonts that come with the THREE.js distribution itself.

If Typeface is down, or you want to use a font that is not there, there's a tutorial with a python script for blender that allows you to export text to Three.js's JSON format: [link:http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html]
BMFonts (bitmap fonts) allow batching glyphs into a single BufferGeometry. BMFont rendering supports word-wrapping, letter spacing, kerning, signed distance fields with standard derivatives, multi-channel signed distance fields, multi-texture fonts, and more. See [link:https://github.com/felixmariotto/three-mesh-ui three-mesh-ui] or [link:https://github.com/Jam3/three-bmfont-text three-bmfont-text].
Stock fonts are available in projects like [link:https://github.com/etiennepinchon/aframe-fonts A-Frame Fonts], or you can create your own from any .TTF font, optimizing to include only characters required for a project.
Some helpful tools:
The [link:https://www.npmjs.com/package/troika-three-text troika-three-text] package renders quality antialiased text using a similar technique as BMFonts, but works directly with any .TTF or .WOFF font file so you don't have to pregenerate a glyph texture offline. It also adds capabilities including:
