Sea Wind Shutters

Sea Wind Shutters is a purposed installation located on the Barcelona Beachfront Passageway, to reimagine the current unwelcoming industrial path that corrals its visitors. Using panels in a wavelike motion, Sea Wind Shutters generates a soft ambient noise from the motion produced from the wind.

1. First we went about constructing a surface on which to form our parametric structure.
2. Once we had a surface we knew that in order to assign extruded panels to the surface we needed to break down the surface into a grid.
3. Using the divide domain component along with the isotrim tool the surface split into segments in which we could extract vertices, curves and centroids.
4. After isotrim, we used the area component to take the centroid in which to plug into a closest surface point component.
5. Next the isotrim surface was then assigned to the closest surface point component in which to extract uv points on the isotrim surface.
6. Knowing that these points rested on the segmented surface of the isotrim we were able to discover normal vectors of those segments. Giving us the correct direction of extrusion.
7. After discovering the direction in which we could extrude our panels, we needed to assign a geometry in which to extrude from.
8. Using the Explode Brep tool we were able to create a list of all the vertices in the surface.
9. With that list of vertices we dispatched in order to generate a pattern from which to interpolate curves.
10. These curves then each had their own branch in which we needed to compile back into a list.
11. We flattened the branches with the flatten tree component in which we used a cull pattern tool on.
12. By culling the pattern of the list we were able to extract a pattern of curves that we extruded our panels from.
13. We referred back to the normal vectors that we had found from evaluating the surface of the isotrim and used them to assign a direction and amplitude for our extrusions.
14. Realizing the panels had no thickness to them, we took the extrusions we had just created and evaluated their surfaces in order to extract a normal vector for each panel to be thickened by.
15. Finally in order to achieve the reactivity of our parametric skin, we chose to evaluate the surface of the original geometry and establish an attractor point on it.
16. Using the distance from the attractor point and the centroids taken from the earlier area component we compiled a list of values that we used to tilt the panels along their axii. 
17. After tilting the panels we assigned a custom preview component to the geometry in order to view the final result.
