Sometimes you need to make groups of objects (it's not conveniently to apply transforms to each object when can make just one to a group). In Three.js you make it using
THREE.Object3D and it's children.
In Whitestorm.js we have
WHS.Group that can do it in two ways:
Adding objects to an empty group
const sphere = new WHS.Sphere(); const box = new WHS.Box(); const group = new WHS.Group(); sphere.addTo(group); box.addTo(group);
Making a group from objects
const sphere = new WHS.Sphere(); const box = new WHS.Box(); const group = new WHS.Group(box, sphere); // OR: const group = new WHS.Group([box, sphere]);
You can list elements in sequence or pass an array. (see es6 rest/spread).
