There was an unexpected idea. I need to show 3D model (scene). I want to create Godot project that will demonstrate the 3D model.

I don’t know how to manage the mouse, which will allow you to rotate, zoom in and zoom out the model. Please tell me how to do it?

My lazy way to do it is:
Create a Spatial over the model and a Camera child of the spatial.
Move like on Z the Camera away from the Spatial
Rotate the Spatial on Y for rotation.
Move the Camera on local Z for zoom.
Always looking at the Spatial.
