The pointing machine (La Machinetta di punta)
is a one to one proportion, duplicating device. Which means
you can only copy an object in relation to it’s own size, but not
enlarge or reduce. The best comparison that can be made is to the
childhood game “connect the dots”. As you connect the different
points in their sequence you come up with a picture. This is
precisely what are you doing only in three dimensions. Where
connect the dots has as an x and y axis describing the exact
location of each dot in relation to the picture plane, the machinetta
method has an x, y and z axis, from which you can locate each
point of an object in relation to the space within a rectangular solid.
