This is the introduction chapter of my latest paper presented at the Nexus 2014 Conference, in Ankara. The paper will be published in the 2015 issue of Nexus Network Journal. Generative algorithms have been integrated to design in a sequential form where text-based scripting languages are accepted as mainstream tools. This approach to design scripting originated from “control flow”, the dominating paradigm of programming languages. Methods of control flow eventually lead […]

Nowadays I plan to enter Rhinoscript, Python, and DesignScript back again. However, I can’t leave Grasshopper3D without mentioning the “cognitive shift” it pioneered in the design computing community. Here is a phrase from a famous special issue of “Computer” Journal, published in 1982 with Tilak Agerwala and Arvind’s editorials; Data flow languages form a subclass of the languages which are based primarily upon function application (i.e., applicative languages). By data […]
In 1982, it has been more than 15 years since the dataflow approach to algorithm designing are discussed in computer science. Computer journal publishes a special issue with the foreword of Tilak Agerwala; he says; …We have discussed two characteristics of the von Neumann model of computation: global updatable memory and a single program counter. It will become clear shortly that the data flow model has neither of these. First, the data flow model […]
Today, we’ve studied fundamentals of component-based design methods. Using curves and surfaces as starting points, we’ve experienced ways of translating those entities via design criteria based on our purposes. First, a curve is used to construct a leaf structure. We’ve experienced dispatching data lists and combining them back together. Subdividing curves into points created further entities such as vectors and planes. We used those entities as inputs of regular drawing […]
Today’s subject was closely related to the one last week; the data list and data tree management. Creating suitable data structures for our purposes is one of the tricky parts of whole Grasshopper experiments. We’ve developed a grid of objects, somehow associated with another one (a curve). Strong emphasis was on the way of thinking, getting back and forth on the process, and the re-definition of data lists. Especially, this […]
Here are some basic references to Grasshopper’s handling of objects. As the most powerful and intuitive part of such Visual Programming Languages is the focus of dataflow, the critical part of it’s education lies at the fundamentals of data tree manipulations. Designers using these tools should understand and predict the type of data trees his/her parametric model would process. Here is the Grasshopper document including these components; [2012_01_10-adding streams] We’ll start […]
Scripting languages have become one of the main environments of generative design since the beginning of the new Millenium. Also as a new research field, design researchers focused on the potentials of this medium. However, this has caused a field dependency on computer programming, as scripting could not be conceptualized by design researchers independent from computer programming paradigms. This leads designers to conflicts of cognitive duality and potential pedagogical misleads. […]
