Two large format digital prints by Paul Hertz will be shown in the juried art show at the annual Computational Aesthetics conference, held this year in Vancouver, Canada from August 5 through 7. The archival inkjet prints from the artist’s recent “Sampling Patterns” series, Ponente and Shimmer, were printed at Ignotus Editions.
Ponente and Shimmer are based on regular random distributions known as “blue noise.” Natural phenomena such as identically charged particles jostling for position within a limiting boundary or a flock of birds adjusting their mutual distances have similar distributions. Blue noise dot patterns have interesting visual and cognitive effects: Their regularity seems to imply an order just about to emerge, which their randomness negates. These and other works in my “Sampling Patterns” series are snapshots from interactive real-time animations where the geometric points of the distribution are used to sample functions that control color, scale, shape, and other visual attributes. The snapshots are further edited to produce prints.
In Ponente, blue noise grids determine the locations of distorted circular shapes in different scales and granularities. Low frequency wave functions control variations in scale and simple coloring rules distinguish different layers of shapes or populations within each layer. In Shimmer, a distribution is partitioned into three populations that are distinguished by algorithmically determined colors. Each population has its own shape-generation rule. A global rule for shape orientation (a wave function) creates swirling motions over the visual field.
