This allowed for more complex and realistic images to be created. In the 1970s and 1980s, AI-generated art began to be used more extensively in computer-aided design (CAD).ĬAD software allows designers to create and manipulate three-dimensional shapes on a computer. Nake commonly used random number generation in his work of this period, and, likely, his multiplication process was partly automated. These signs were then placed in a raster according to the values of the matrix. ‍Nake produced a square matrix and filled it with numbers, which were multiplied successively by itself, and the resulting new matrices were translated into images of predetermined intervals.Įach number was assigned a visual sign with a particular form and color.
