WooJae’s Blog ARTC O P E N S Y S T E M S Iteration in Grasshopper (Without scripting) « Heumann Design/Tech Lately I have been experimenting with iteration in Grasshopper. Iteration is often thought to be synonymous with the computer programming concept of a loop, but while the concepts are related, the definition of iteration I will use requires that the results of one iteration are used as the starting point for the next iteration. A loop can simply be a way to apply the same operation to a list of elements (much like processing multiple values with a component in grasshopper), but it is an iterative loop if the results from one step are used in the calculation of the next step (something grasshopper does not directly do.) This concept is also tightly linked with the concept of recursion. Simply stated, the definition of a recursive function includes the function itself. Fractals are among the canonical examples of recursion in mathematics and programming. Achieving either iteration or recursion in Grasshopper would seem to require the use of scripting.

Grasshopper Resources Generic Explorations Grasshopper – Obleo Design Media From Top Down to Bottom Up Generative design tools flip the script of architectural thinking by Brett Duesing, Obleo Design Media “Some might view computational design is just making some weird or crazy form,” says architectural designer Woo Jae Sung. Designers have two different starting points when conceiving new structural forms, top-down and bottom-up. Bottom-up conceptual approaches are found throughout other art disciplines, but it is still rare in architecture. “In my perspective, the generative design process is not a sub-discipline in architecture, but rather another paradigm,” says Sung. Sung publishes his own Grasshopper Tutorial, a primer of getting started in the program, for Rhino users everywhere. “Before the advent of parametric and generative tools, doing bottom-up design was a time-consuming, painful, and rigorous process,” says Sung.
