How to center a rotating model?

Question

JavaScript

There is a rotating dot cube - https://codepen.io/anon/pen/NZKQVq?editors=0010
It rotates around some axis outside of it.
There is also a ball (which was roughly and not skillfully converted into a cube from the link above) - https://codepen.io/team/basedesign/pen/NoPZyQ?edit...
It rotates around its central axis.
How can I make the cube rotate in the same way?

Answer 1

The coordinates of the points are random values ​​in the interval -/+ half of the side of the cube.

UPD. And you can also do this - we assign an extreme value to one of the coordinates (selected randomly), then the cube will be empty inside, all points on the faces . If you fix two coordinates - all points on the edges .
