3D representation of the Mandelbrot set

A new 3D representation of the Mandelbrot set is presented. Although the method employing the Douady Hubbard's potential function has been useful for the 3D representation of the Mandelbrot set, in our new method 3D pictures are generated by setting height components normal to the plane of the original Mandelbrot set. The pictures obtained look like natural landscapes with cliffs.

Designing emotional, metaphoric, natural and intuitive interfaces for interactive art, edutainment and mobile communications

We are artists working since 1991 on the creation of interactive computer installations for which we design metaphoric, emotional, natural, intuitive and multi-modal interfaces. The interactive experiences we create are situated between art, design, entertainment and edutainment. When creating our interactive systems we often develop novel interface technologies that match conceptual and metaphoric content with technically novel interface solutions. While our main focus is to design interactive systems for the art context, our interactive or immersive systems also often find use in edutainment and in mobile communications areas. The following article summarizes some of our key concepts for our interface designs and presents some of our interactive technologies in more detail.

Digital media: Bridges between data particles and artifacts

The field of visual communication is currently facing a period of transition to digital media. Two tracks of development can be distinguished; one utilitarian, the other artistic in scope. The first area of application pragmatically substitutes existing media with computerized simulations and adheres to standards that have evolved out of common practice. The artistic direction experimentally investigates new features inherent in computer imaging devices and exploits them for the creation of meaningful expression. The intersection of these two apparently divergent approaches is the structural foundation of all digital media. My focus will be on artistic explorations, since they more clearly reveal the relevant properties. The metaphor of adata particle is introduced to explain the general universality of digital media. The structural components of the data particle are analysed in terms of duality, discreteness and abstraction. These properties are found to have significant impact on the production process of visual information: digital media encourage interactive use, integrate different classes of symbolic representation, and facilitate intelligent image generation.

Techniques in computer art

The major techniques in computer art in use so far are classified into six categories and evaluated. Among these categories, we discuss the function method in detail by showing pictures generated by our system ART-3, a small system based on the function method. By this means we show the usefulness of mathematics in this area and demonstrate the enormous possibilities of computer art. Furthermore, on the basis of our experience of using ART-3 the role of artists in technology-aided art is briefly discussed.
