The method of producing in a solid body a three-dimensional representation of an audio and/or video signal consists in this order: - in recording the signal on an appropriate magnetic medium, - in digitizing this signal, - in applying to the result of this digitization, a processing aimed at transforming the binary data previously obtained into decimal data, - in transforming these decimal data into complex data, - in applying a Fourier transform to these complex data, - in generating from the data previously obtained a computer file useable by a numerically controlled machine with a view to the production by this machine of the three-dimensional representation. |
