The biomorphic pavilion is an architectural structure produced by a generative design process that aims to generate human structures through a biological perspective. Biological structures achieve their ecological standards by using a particular design process. This process imposes a morphological identity on its structures, which means that ecological shape follows a particular geometric pattern. The pattern consists of a set of geometric qualities that follow a set of structural organization requirements. The biological structures are generate through the addition of elements (polygons) with the same geometric familiarity but proportionally different. Each element contains its own rules and cannot be part of another. The elements boundaries are perfectly delineated, irregular and follow a local symmetry pattern. However, these structural shapes cannot be arranged randomly in space. Its spread requires expansive organizational shapes as growth guides (spiral and wave). In order to generate elements dependency the distribution imposed by the expansive shapes requires a gradient pattern. This distribution highlights the shape origin and gives it structural equilibrium, i.e, all the structural elements are organized for a common goal.
Decoding this pattern in geometrical rules and organized them through a generative process is relevant to increase the biomimetic level of the biological inspired design in morphological terms. The design process allows to generate shape diversity with biological identity and without directly copying biological shapes. The shape generation based on a growth process allows the architect / designer to deviate from the existing shapes and generate others with the same morphological coherence.
The biomorphic pavilion is an example of the shape diversity able to be generated with this drawing tool and without the necessity of reproduce an existing biological structure. The composition reveals all the geometric qualities mention before. The structural elements are polygons organized through a wave expansive shape. They also are organized by a gradient cadence in other to highlight the center. The irregular symmetry and the similarity by shape familiarity it is also present. The result is a composition with structural fluidity able to generate a force field. The transposition of forces with the surroundings allowed by the structural organization, transforms the shape morphology into a participatory structure and not as a barrier. Despite its complex geometry the structural fluidity of this shape allows its easier interpretation and strongly affirms its origin in the surrounding.
The generation of architectural structures with the geometric pattern of biological morphology allows to achieve shapes with the following ecological qualities: 1) multifuncionality – shape is simultaneously a structural element and a self supporting structure; 2) material optimization – shape generation with a single material and by modular construction.
To control the order behind the shape irregularity and its transposition to a real model, parametric digital tools are required. The 3D printing and robotics will be a real asset in the fabrication of these structures. Biomaterials will be another component to take into account in the development of the manufacturing process.
