Parametric Modeling with Grasshopper
Form-finding techniques via GH definitions used in conjunction with patent pending joint technology enable the creation of almost endless forms as real structures.
I have developed a design and construction system which allows an affordable way to fabricate architecture-scale biomorphic forms, specifically all-glazing structures. This effort is part of a strategy for fostering closer ties to our natural environment through direct immersive experience and the engagement of biophilic concepts, which have been proven to enhance one’s health, happiness and cognitive performance. The design process utilizes Grasshopper parametric design software to enable a novel method for creating structural systems, which enables the creation of irregular geometric forms and structures. Making amorphically shaped modular systems is an intriguing endeavor, though most designs stop at the model phase, as turning those models into reality is often cost-prohibitive since joinery methods are usually geared to repeating or fixed geometries. Thus irregular systems usually cannot reap economies-of-scale benefits associated with modern mass production techniques.
In practice the geometric relationships between mesh faces are used in conjunction with the construction system (pat. pend.), which was created to accommodate the assembly logic of these faceted forms. The Grasshopper definition dissects the geometry, then dictates exact and specific cut paths for digital machinery to create the parts needed to assemble unique and specific joints from sheet stock material and tubing. This enables almost endless form creation while maintaining affordability. Form-finding techniques range from 3d scanning plasticine models to parametric physics simulation. For the dome structure presented here, a relationship was explored between two contrasting shapes, both of which are largely utilized as greenhouse structures: the sphere (geodesic dome); and the cube (most constructions). Superimposing one onto the other, the vertices of the cube acted as magnetic point forces to morph the dome. These points pushed or pulled the dome into a new form, one which this system of construction can create. The Karamba plugin for Grasshopper was then used to assess relative structural integrity of the assembly, and inform the need for support, material strengthening or design modifications.
