You can use tools like this to draw custom BDF fonts in real time inside a THREE.CanvasTexture

I want to add a large number of sprites. For performance reasons, I chose to use instancedMesh and shader to implement them. However, if each sprite generates a texture, the performance is relatively poor because many words are repeated. Therefore, I drew all the words that appeared on a canvas and wanted to display the sprites through UV
