STL Loader kept spinning - stl

Question

I am using three.min.js and works beautifully but the model is spinning endlessly. How to stop it and allow user to spin manually? And the spinning is off centered also, is there away to resolve this?

Answer 1

to stop it from spinning just remove the:
var timer = Date.now() * 0.0005;
camera.position.x = Math.cos(timer) * 3;
camera.position.z = Math.sin(timer) * 3;
from the render function or make a function to enable this part on click.
