0.0 FOREWORD With my architectural approach I aspire to represent such a system, in which random processes are running within a logic of incontestable rules. The inspiration for this thesis I found in works of Jackson Pollock, particularly they were perceived as architectural drawings. As an evidence of presence of graphical dominance in this images can serve the choice of color: coal black, sienna brown, dark green; thous colors one can as well find in any technical drawing, where color is conditional to the established notation system. Therefore, this works can literally be considered as encoded drawings, presumably spatial diagrams, which somehow can be decoded into architectural treatises. And so, aiming to achieve an architectural technique, in which shape and structure would be correlating to expression of those works, the research was launched.
1.0 RESEARCH This reasearch was initiated by a material experiment, where an irregular spatial structure was extracted out of a solid body of a Styrofoam panel. With a goal to avoiding any narrative expression, the structure was developed only on the basis of the preexisting context of a certain region and so emphasized a shape that was emerging mostly by itself. Within a translation of the emergent structure into geometrical language, was found a pattern that is not describable by any algorithmic expression. In order to compress the collected data, the initial object was described in a format of specifically invented notation system, that cptured interrelations between existing nodes. Following elaboration of the subject was focused on this node areas, abstractly conceived as points, which were defined by sets of three dimensional coordinates. For its digital simulation was used an algorithm of generative isosurface that equally retreats from an abstract axial carcass of an item. In architectural terms this node areas represent joints, and in the found structure their phenotype by itself is unpredictable, however it is computed out of the context that a joint belong to.

1.2 ADEQUATE COMPUTATION METHODOLOGY After the definition was given to the subject of study, the major effort was directed towards parametric simulation of correlating structures. Quite soon was created an algorithm based on OMEGA-involved spatiel distribution of points, then established proximity network and finaly generative isosurface which uses this linear carcass as the axial scheme of the outcome structure.

1.3 MATERIAL SYSTEM The final challenge of the research was to reproduce the process of computed morphogenesis in a physical experiment and on its basis to develop a material system for efficient fabrication of such items. As a potential way to physically simulate the process was considered a thermodynamic interaction between hot wires and meltable materials, such as ice, wax or cured gelatin solution. First experiment with ice approved the feasibility of the simulation. With a direct current of electricity which heats metal wires tunnels inside of a solid block of ice can be melt within fairly short time frames.

1.4 TECHNOLOGY Further with a goal to produce a castable mold, ice was replaced by cured gelatin. The pilot experiment with gypsum captured two types of possible products: the first type has loose wires and so represents a non-regular curvature along the surface, the second with rigid straight wires leads to predictable and precise outcome. The final model is a sample of space frame structure based on irregular joints. For this model joints were produced out of Epoxy resin.

2.0 PROPOSAL: THE ATMOSPHERE PROJECT The Atmosphere project creates a space with variable air pressure conditions. It is design to serve for two purposes: simulation of low atmospheric pressure for mountaineers and offering a medical serves for hypertensive patients, creating a stable pressure in times of low or high conditions of such in nature. The architectural approach aspires to represent such a system, in which random processes are running within a logic of incontestable rules. For that reason this very project is designed to establish a mental connotation between an irregular network and a metaphysical idea of a sphere, to somehow link together abstract and figurative.
