In the previous chapter, we defined the design process for connective joints in spatial reticular structures with rods made from bamboo culms. The following chapter, on the other hand, analyses a series of themes related to the design and optimisation of a free-form structure. Once the form of an NURBS mathematical surface has been determined, we investigate the main techniques for subdivision of discrete elements with dimensions adapted for manufacturing and assembly (paragraph 4.1 Digital representation techniques, NURBS and Polygon Mesh; paragraph 4.2 Optimisation of surface tessellation). The discretisation method of a planar surface based on Voronoi diagrams is detailed further (paragraph 4.3 Natural patterns, the Voronoi diagram Particle-Spring System and definition of the structural grid) by optimising the distribution of the cells in the pattern with form-finding techniques, in order to satisfy structural requirements (the algorithm used is the Particle-Spring System, by means of the Kangaroo plug-in for Grasshopper, which was developed by Daniel Piker). In the last Sect. 4.4, Definition of the numerical model and structural optimisation through the Galapagos evolutionary solver, the diagram is applied to any free-form surface by iterating an algorithmic process to develop the best geometric-spatial configuration that satisfies certain threshold values.
