How to make the model rotate in the direction of the mouse

Questions
1

I have implemented a.STL model rotation, but it seems to rotate around the dots, and I want it to rotate in the direction of the mouse, such as pressing the left mouse button to slide from right to left on the page, and the model rotates from right to left.
my code is here.
