Generative art evolves day by day, along with technology. To excel in this type of art it is necessary to imagine new and original programming methods. That's what GA3D is all about, the ability to apply algorithms and codes to three-dimensional planes. Some of the unpredictable results of the numerical and chromatic variations used in the set resulted in "Brooding", a work where volume and voids mix with a surprising and mysterious visual result. After visiting some of the most important collections of generative art, I found nothing like it, which motivates me to think that GA3D (Generative Art 3D, or Spatial Generative Art) can mark a new chapter in the development of this exciting artistic method.
