Shader is a design proposal for a new type of shading structure in which the design and manufacturing methods are based on a generative, performance oriented digital approach.
The design process employs simulation in a “before-the-fact” manner, which generates an initial form directly from programmatic information. The initial design stage employs an algorithm, which creates a spatial shading envelope based on the desired time frame and the dimensions of a shaded area. The initial envelope is used as an input for a secondary, form finding process, which employs a gravitational cloth simulation.
The secondary envelope, which embeds material properties, is then optimized via a structural analysis in terms of loads, tension and amount of material. The envelope is manufactured with a multilayer fiber glass fabric, which is hardened by an epoxy resin in a heating/curing process. In order to avoid the redundancies in the traditional use of molds the curing process is performed while the fabric is hanged upside down from predefined points.
