3.7 DESIGN DEVELOPMENT THROUGH SCRIPT

To further understand the rotational movement of this geometric form, a 3-D model was generated through an algorithmic script in Grasshopper, a visual scripting software used as an extension to Rhinoceros. From the previous sections, it is clear that OSTRA is a spiral shaped structure that rotates in a sequence.

The base model was generated based on a spiral shape that is asymmetrical in shape with a maximum diameter of 5 meters and a minimum of 3 meters. Once the curve is created, lines are constructed connecting 12 points on the curve to the center of the circle.

As the lines are obtained, they are converted into rectangular blocks that form the spine of the fins.

The problem to be solved was creating a sequence of movement that allows the fins to move after every 30 degrees of rotation. The script used and situation, where the top fin moves only once the bottom fin, completes a 30-degree movement from its initial position.
