Above: top & bottom surface reconstruction

n|Edg” assembly is written within continuous series of investigations at different scale:

– the overall: development of protocols of surface relaxation – in order for the surface to generate best fit curvature in response to fix hanging or support points (floor, ceiling, walls) as curvature – despite generating apparent complexity – also provides natural structural stiffness.

– surface description (or sampling): re-understanding the resultant surface as series of points – which densities are relative to the degree of curvature – the more curvature the more points and eventually parts.

– surface reconstruction (or tessellation): previous work focused on describing complex surfaces with flat components – after working for different “high end” architectural and design practices – the only way to keep pushing non standard environments is to introduce the economy of parts as part of the equation – therefore early tests were first looking at ways to triangulate complex surfaces – and therefore strategize on panels cut within flat sheets of material – which very quickly evolved toward what is now the trendy “arrays of quads” components paradigm. “n|Edg” is now investigating the reconstruction of a surface with polygonal parts going from three edges to (n) number of edges.

– informed customization: each part is similar though not identical – its change of size and proportion is therefore allows to describe different radius of curvature – but also local re-reading of orientation is driving the length and width of branches – the flatter, the wider in order to provide more surface alike coverage.
