We describe a novel technique for the fast production of large point sets with different spectral properties. In contrast to tile-based methods we use so-called AA Patterns: ornamental point sets obtained from quantization errors. These patterns have a discrete and structured number-theoretic nature, can be produced at very low costs, and possess an… (More)
" AA Patterns " is the collective name of a recently introduced algorithmic art, where a simple affine 2D transformation is employed to generate aesthetic patterns. AA Patterns are controlled by a single real parameter between 1 and 2. This paper presents examples of how mathematical analysis can help in selecting and tuning the pattern parameter in such a… (More)
A thorough comparison is made between the different implementation schemes of Space-Time and Space-Frequency Block Coded OFDM, showing the features of each alternative, and suggesting typical situations where it excels. New designs are also introduced to complete the comparison set. The issue of mixing diversity modes is addressed, too.
We present a new idea for the algorithmic design of weaving patterns that is based on AA Outlines. The method takes advantage of their inherent property of having only a few distinct rows and columns. In contrast to a prior Bridges paper, we describe a new approach for extracting weaving patterns from AA Outlines, and we add colors of yarns as a design… (More)
We explore the use of Truchet-like tiles (tiles with half area shaded) for single-tone (monochrome) line-based rendering of maps. We borrow concepts from information theory to develop some qualitative and quantitative measures, and use them to discuss four rendering styles which use Truchet-like tiles. We first present a style based on the original Truchet… (More)
We present a new approach for stippling by recursively dividing a grayscale image into rectangles with equal amount of ink, then we use the resulting structure to generate novel line-based halftoning techniques. We present four different rendering styles which share the same underlying structure, two of which bear some similarity to Bosch-Kaplan's TSP Art… (More)
