ABSTRACT:
A method of producing a bas-relief with a motif which varies with the light, characterized in that the original motif to be reproduced is divided into a grid. The intensity of the grey in each of the divisions of the grid is measured. A numerical value is assigned to each division. The numerical value represents an intensity of grey and corresponds to an element of the bas-relief. The elements of the bas-relief, in accordance with the way in which the grid is divided, are placed side by side in a manner such that the light rays simultaneously make surface shadow spots appear on each element of the bas-relief in accordance with the intensity of the grey of the original motif. The composition of the spots is seen by viewing the bas-relief from a distance and reproduces the original motif.
