How to add a text box after specific areas on the 3D object?

Hi,

I am working on a skeleton 3D object.

My issue is that whenever I click on some areas on the 3D object I need a text box to pop up on the screen.

Help me with this issue.
Thank you in advance.

Assuming you’re using raycasting to handle clicking in 3D - you can create a CSS2DObject (example) and just place it at the position of ray intersection.
