Week 04: The Mathematics of Nature

With recent computer programs such as Grasshopper, there has been an explosion of futuristic//organic//downright bizarre building facades and ceiling canopy designs. Concept Tower by Valerio López Acevedo. Software: Grasshopper Vray Autodesk 3ds Max Rhinoceros 5.5:

Most popular appears to be the use of fractal geometry to generate patterns. This approach mimics the generation of crystals and cauliflower. I have seen this image below of Romanesco Broccoli on numerous inspiration boards in studio…it seems to be the go-to parametric veggie.

ArchDaily terms this parametric approach “Scriptism” or “computational design.” These designs can be very successful, and create a responsive architecture that reminds us of patterns in nature. It is important; however, to make sure these designs are purposeful…and not just created randomly and for the sake of ‘looking cool.’

Case Study: A Pavilion Inspired By the Sea Urchin

ITKE University of Stuttgart, Germany

The Institute for Computational Design (ICD) and the Institute of Building Structures and Structural Design (ITKE), together with students at the University of Stuttgart developed this temporary structure in order to explore bionic architecture and computer-based fabrication methods. The pavilion is created by ultra-light plywood “shells” held together by finger-joints. The design of the modular units was inspired by the sand dollar, a sub-species of the sea urchin (Echinoidea).

The modules morph and “grow” according to a natural pattern programmed into the computer.

“The cell sizes are not constant, but adapt to local curvature and discontinuities. In the areas of small curvature the central cells are more than two meters tall, while at the edge they only reach half a meter”

If used intelligently, fractal geometry and parametric modeling can create spaces that not only enhance the human-nature connection, but also generate less waste and function efficiently.
