Artificial Processes - Algorithmic structures


On a theoretical- practical/ experimental way research is done after the possibilities of sensor- and computertechnology for
artistic purposes. The essense of the works lies in real-time accomplishable computermodels; 'algorithmic constructions'
defined in code, which make possible that artificial processes and generative systems can excist, develop and function as
autonomous entities.

These artificial, purely formal, systems and processes generate behaviors which manifest in structures and forms in images.
The code is matter, the buildingblock for construction and forms the blueprint for the actual artworks.


The works are catagorizable in various classes:

1 ) Works in which form-collections and series of form-variations are being generated and shown as screengraphics or as prints.
    By random or systematically changing the parameters of the algorithm the combinatorical space of the algorithm can be
    explored, which results in static graphical images; line-drawings or three-dimensional forms.





2 ) Works which are continuously developing and whereby the unique temporary state of the real-time dynamic generative proces
    is being visualized. The course of the process is totally defined by the generative model without influence from outside the
    system; the algorithm describes the complete complex-dynamical process. This results in endless sequences of images;
    form-variations which develop in a step-wise manner and generate organic forms and tempo-spatial constructs.

    I determine the rules and artistic boundary conditions, the computerprogram excecutes these sets of instructions. The code
    autonomously generates sequences of (video)images which represent a richness of variations which are not foresee-able
    beforehand.

    In the serie 'Hypergraphia', (Hypergraphia is an overwhelming urge to write. It is not itself a disorder, but can be associated
    with temporal lobe changes in epilepsy and mania in the context of bipolar disorder. Neurologist Alice Weaver Flaherty, in her
    book The Midnight Disease: The Drive to Write, Writer's Block, and the Creative Brain, describes its relationship to writer's block
    and to compulsive reading or hyperlexia. (wikipedia))

    It is an attempt to control these mania or urge by automation. This results in endless variations of graffiti- and calligraphy
    resembling forms.


    The serie 'Reaction-diffusion', is based upon a mathematical model which simulates the interaction of multiple substances
    based on two simple rules: a) local chemical reactions, whereby artificial substances(dye) react opon each other and thereby
    transform, and b ) The spreading of the substances (diffusion) in an artificial substrate; These processes are taking place in the
    realworld when we release a dye in a liquid, or is seen in aquarelle, in this model the characteristics of liquid are also being
    modelled (with characteristics like pressure, viscosity etc.) which makes possible specific pattern formations; phenomena like
    waves, interference and morphological segregation. In this specific manner (by modelling physical characteristics) abstract
    organic images emerge, which origin and orgination is not directly obvious.






3 ) Works which are calculated in real-time and from which the parametrizations can be varied dynamically by interaction.
    The artwork is no longer a statical object or a pre-defined multiple-choice interaction, but a process-like 'living' system,
    the artwork is characterized by the complex interrelations and interactions of real- and virtual entities; like processes of
    continous change, adaptation and evolution.

    These installations are integrated in the urban, architectonical space or presented in a monumental ways in galleries. There
    are many possible ways of placement and ways of interacting with these works dependent on the nature of the work and the
    specific placement different techniques can be applied.

    An example is a image-synthesizer which enables visitors to compose abstact images via an electronic interaction device,
    the combinatorical space is extremely large, so the visitor can experiment endlessly.

    Other more advanced interactive works use computervision ( Computer vision is the science and technology of machines that
    see. As a scientific discipline, computer vision is concerned with the theory for building artificial systems that obtain information
    from images. (wikipedia)).

    Computervision makes possible to extract the movement, position from live-camera images, this information can be fed back
    to a computermodel, and the shown visualization can adapt and progress according to the changed (spatial) situation.

    This enables the visitor/ passer-by to manoeuvre a virtual scene soley by body movement (without a physical/ technical-
    interactiondevice.), or the position or movement is less literally of influence on the state and course of the work.

    In this manner passers can be accidentally or actively associated with the work, whereby the focus changes from the object
    towards participation in a process of play and multiple ways of interaction, which provides the work with extra complexity.
