![]() ![]() Thus, if you want to draw five circles in a regular way, you must be able to do it without using trigonometric formulae to figure out where these circles have to be drawn. This is even more true because our visual perceptive chain processes its inputs in a relative way, as paradoxical visual games highlight it.Īs a consequence, XRVG strives to get rid of these absolutes, by using shapes and functions as numerical patterns to compute shapes and composition. It is not their absolute values (that is absolute spatial and color coordinates) but their relations that matters. What that means is that if you want to do graphics programming with them, you rapidly get lost in a list of basic drawing primitives with lots of numbers, without being able to recover the abstract compositional content of the graphic.Īctually, a graphic is foremost a composition of basic shapes and color. Nearly every programming toolkit that you may find, in any programming language, instanciates shapes with absolute geometrical coordinates. #Nodebox mandelbrot softwareNodeBox is a new software application for creating generative art using. I’m quoting liberally from this, because it’s really fantastic stuff that speaks well on behalf of context-free art kits. Evolutionary Music and the Zipf-Mandelbrot Law: Developing Fitness Functions for Pleasant Music Bill Manaris Dallas Vaughan Christopher Wagner Juan Romero Robert B. XaoS can display many different fractal types, including Mandelbrot, Barnsley. Toward the middle of the philosophy page, XRVG’s author Julien Léonard goes into a very compelling rationale for why XRVG strays from using coordinate systems. ![]() XRVG is a response to “the frustrating magical aspect of generative fractals like the Mandelbrot set” and, perhaps even moreso, “the hermetique aspect of the dominant graphics programming toolkits notation.” You get the sense this fellow’s trying to work out new ways to express shapes, particularly generative shapes like fractals.Īnd, for further study, I highly recommend the author’s blog of fractals, which he has filled with nearly 200 samples throughout the year. Let me give you an idea of the mind at work behind this. Our finding that visual recursion can be represented without access to verbal resources suggests that recursion is available independently of language processing abilities.While plundering around in the NodeBox forums, I happened upon a very stirring library for creating SVG drawings in Ruby. Our results show that the ability to acquire and use visual recursive representations is not affected by the presence of verbal and motor interference tasks. We tested participants across 4 conditions: (1) Visual recursion only, (2) Visual recursion with motor interference (sequential finger tapping), (3) Visual recursion with verbal interference – low load, and (4) Visual recursion with verbal interference – high load. The english version of Digimag 21, Italian monthly e-magazine of digital culture and electronic arts, is available online. Networked Video in 10 Years : Networked Video Parseable Video. With this definition recursion can be distinguished from general hierarchical embedding. artificialeyes with Telefon Tel Aviv for Burn Babylon, Istanbul. Even something like Mandelbrot or Julia sets (or similar fractals) are fully deterministic algorithms, but the choice of the position and scale (quite a small initial input) is sufficient to generate a large variety of interesting results > procedural generation. We define recursion as the ability to represent multiple hierarchical levels using the same rule, entailing the ability to generate new levels beyond those previously encountered. In this study we use a dual-task paradigm to assess whether verbal resources are required to perform a visual recursion task. We describe a new method to explore recursive cognition in the visual domain. If so, linguistic resources should inevitably be activated while representing recursion in non-linguistic domains. The ability to form and use recursive representations while processing hierarchical structures has been hypothesized to rely on language abilities. ![]()
