title: Use JavaScript arrays instead of loading OBJ or GLTF in three.js for performance
body: <p>Loading OBJ/GLTF/GLB models into my three.js application takes some time, while declaring JavaScript arrays of vertices and indices of the same data and creating a new object is much faster (and less file size).</p>
  <p>Is this good practice however? Is there a compelling reason as why to load a 3D file format instead of using JavaScript arrays which seem faster?</p>
