Shopify Threejs change textures and engraving on glb 3d model

Hi, we are developing a store in shopify that is going to have 3d model visualization with threejs. We need a few things.

- Camera control, when the user start to type on input camera should go to a front position.
- The text of the input will update and appear on the 3d model on a specific location.
- The selected color will change the texture on the 3d model.

Please show us examples of what you did.

Thanks
