Use canvas 1 to create sprite 1, 2, and 3, Use instancedMesh shaderMaterial
canvas
sprite1
sprite2
sprite3
Atlas data
You can use tools like this to draw custom BDF fonts in real time inside a THREE.CanvasTexture
Then THREE.InstancedBufferAttribute to change lines between instances.

Therefore, I drew all the words that appeared on a canvas and wanted to display the sprites through UV
