AB  - The concept of L-Systems was created as base for axiomatic theory of biologic growth. L-systems are applied in computer graphics for fractal generation, as well as in models of biological structures and simulations of their growth. Within generic architecture, by applying L-systems, the natural growth mechanisms are used as generators of architectural geometry. After mathematical and logical explanations of the chosen generic concept of L-systems, this study examines its generic potential, which is the base for development of specific explorative tools in the field of architectural geometry. Within a wider research activity titled 'Generic Explorations', the original software parametric tools have been developed, allowing generation of a complex architectural geometry based on the concept of L-systems. Variation of parametric values facilitates creation and further exploration of generated spatial forms. The paper presents possibilities of developed explorative tools, their particularities, as well as an overview of their initial application results.
AB  - Koncept L-sistema nastao je kao osnova za aksiomatski zasnovanu teoriju biološkog razvoja. Svoje prve neposredne primene L-sistemi nalaze u okviru kompjuterske grafike za generisanje fraktala i u okviru vizuelnih realnih modela bioloških struktura i simulacije njihovog razvoja. U okviru generičke arhitekture, primenom L-sistema, mehanizmi procesa rasta u prirodi koriste se kao generatori arhitektonske geometrije. Posle matematičkih i logičkih objašnjenja generičkog koncepta L-sistema, u radu je razmotren generički potencijal, što zajedno predstavlja osnovu za razvoj eksplorativnih alata u oblasti arhitektonske geometrije zasnovane na konceptu L-sistema. U okviru šire istraživačke aktivnosti pod nazivom 'Generička istraživanja' razvijeni su originalni softverski parametarski eksplorativni alati koji omogućavaju generisanje kompleksne arhitektonske geometrije zasnovane na konceptu L-sistema. Varijacija parametarskih vrednosti omogućava istraživanje prostornih formi koje nastaju na osnovu ovog generičkog koncepta. U radu su prikazane mogućnosti razvijenih eksplorativnih alata, njihove specifičnosti i uzajamne razlike, i dat je osvrt na rezultate njihove primene.

AB  - The self-replicating systems introduced theoretically by von Neumann, are widely examined in biology, computing, geometry, engineering sciences etc. In this study the authors are focused on the concept of cellular automata (CA) and its possible application in processes of spatial form generation. The study has been realized with participation of 60 senior architecture students, creating various spatial forms by using the CA concept, within the series of elective courses titled Generic Explorations. The experimental activity is supported by the software Fun3D, i.e. its CA module, which has been created at the University of Belgrade, Faculty of Architecture, to support generative processes in the field of architecture. After introducing a general idea of the self-replicating systems, the authors explain the major principles of CA, particularly the issues of layered 2D automata, discussing possible approaches to spatial form creation. The study examines CA based on a cubic cell, evolving to a rectangular cuboid where width/height/length ratio can differ, as well as the gap between cells and some of the visual features, like color, transparency, texture etc. Creators of various spatial forms can set a pattern of initial cells, and define a rule for a self-reproduction of a single cell. Combinations of multiple CA systems have been introduced, as an entirely original approach to the problem of form generation in general. A variety of approaches to the generation of spatial form, resulted from the experimental activity, indicate a significant potential of the CA concept application in many areas of spatial design. The authors suggest a range of interpretations of a resulted generic form, such as architectural, urban, product design, exhibition systems etc.
