The project uses generative computational strategies to generate series of special stream paths within 3D space frame, giving it structural stiffness and aesthetic values. The generative algorithm is based on use of multi-agent systems, shortest path calculation, lattice stigmergy and structural analysis. The goal is to create continuously thickened bundle paths within the fuzzy 3D space frame structure, where the bundles double as camouflage and reinforcement for the joints/seams between the welded components, allowing for fabrication of large scale structures, mediating between the discreet components and continuous system.Space Stream is a student project which aims to explore influence of rule-based design systems on low-tech fabrication technique of welding. The research concentrates on wireframe structures, which are strengthened through subdivision of basic geometrical units and bundling and reinforcing of the main structural strands. The custom software used for this project is centered on Dijkstra’s shortest path algorithm in combination with agent-based modeling techniques.
