なぜTypeface.jsonを使うのか？
Standard web fonts (WOFF/TTF) cannot be directly extruded into 3D geometry in Three.js. They must first be converted into a geometric description format called `typeface.json`.
This converter handles that process for you, creating a file that contains all the path data needed to generate 3D text meshes in your WebGL applications.
