title: Centering and Resizing GLTF models automatically in Three.js
body: <p>After downloading 3D models from sketchfab.com and importing them into a Three.js scene, they are most of the times not centered and their size is very big.</p>
  
  <p>Is there a way to automatically center and scale gltf models using a script or a software (working on Linux) or otherwise to do it on-the-fly in Three.js and having the camera to move around the object using OrbitControls.</p>
