Lumius: arte generativa audiovisual em plataforma embarcada

Abstract

Generative art refers to any artistic practice in which the artist uses a system, such as a set of rules in natural language, a computer program, a machine, or another procedural invention, which operates with a certain degree of autonomy and contributes to or results in a finished work of art. The relationship between art and technology is characterized by a continuous process of adaptation, combination, and reinvention, where technical advances create space for new forms of creative expression. This work investigates the potential of generative art and seeks to understand the possibilities of artistic creation mediated by computers, especially in contexts with computational constraints. This work presents the interactive audio-reactive system called Lumius, running on a Raspberry Pi 4. Developed in C++ using the openFrameworks library and OpenGL ES, the project resulted in seven customizable artistic pieces. Four generative visuals respond to music by analyzing spectrum, energy, and beats, while three hybrid compositions combine camera feed with audio.
