9.5 Generative art

Generative art emerged in the 1960s as artists began exploring computer technology to create art. This shift challenged traditional artistic methods, introducing algorithmic and computational approaches that redefined notions of authorship and creativity.

Key principles of generative art include randomness, iterative processes, and parametric design. Pioneering artists like Vera Molnár and Georg Nees established foundational techniques that continue to influence contemporary practice, pushing the boundaries of technology and aesthetics.
