Project 02.03 Generative Design in Nature
    Matthew Dunham

    Taking nature’s (rural location) most reoccurring geometry, the circle, generative design translates what is simple into a vigorous array of geometries all radiating around the initial circle. This model was created in essence that the client be Mother Nature or the natural ebb and flow of the environment and plant matter on Earth. The best example would be how a flower begins as a seed, germinates, and through morphology becomes something greater than the initial seed. Plant-derived cellulose is a structure which is created to be flexible and adaptable made up of thousands of identical linear geometries (cells). Like the grasshopper model which can generate from simple (with voids) to tight and compact, as the client desires. The system which controls these formations, once created, is easy to adapt. The client (nature), in theory, makes changes to the (model-Rhino), and generatively produces  a modified form.

    *The images displayed are intentionally not rendered as to establish a bearing [scale, angle and transformation] using transparency and the base grid found in the files working planes. Displayed below are screen captures for this precise reason.

    Modeling in Rhino and Grasshopper enabled a simple array of a geometry (Y) around a circle (X)  most visible in Figure 03.02. The Main Circle Radius (X1) is on a number slider from 1-100 and dictates the overall size (Figure 03.06, smallest radius), while the Number of Divisions (X2) dictates the number of geometries which will be arrayed around the circumference (Figure 03.02 compared to Figure 03.09). Moving on to the geometries, the Geometry Radios (Y1) dictates the radius of the geometries and is a number slider also set at 1-100. The Geometry Number of Sides (Y2) controls if the shape is as minimal as a 3 sided triangle or a circle made from 100 segments (therefor this is also a 1-100 number slider). The last two most critical components to the generative nature of model is (Z3) the Main Radius Tilt Factor which is on a number slider (1-10) and allows (X) to tilt in factors of 90 Degrees. This component is what introduces the undulating pattern in the circle, most visible in Figure 03.04 and Figure 03.07. The final element (Y3) Thickness of Geometry controls the thickness of each division, this is on a number slider of 1-5.
