English: This shows the process of "pointing", the traditional method of making exact copies in stone carving. A point machine is used to measure points on the original sculpture(seen on the right) and transfer those points onto the stone copy (left). Here we see the very early stages, where points have been measured and marked on the stone copy. These markings point out the high points of the surface so that the stone carver knows which surfaces to sink and which to leave alone.
