Text over 3D model

I have loaded a 3D model and now I want to add dynamic text over the model just like texture to a very specific area ( part ) of the model by clicking on that part, I am using fabric js to achive this. [ If an user want to add more text on that model then he can add text to some other part of the model. and the text must be dragable like in fabric canvas.
image-text
]

But where no Questions attached :eyes:?
