Modeling a Parametric Structure
- I created a parametric structure defined by three lines that functions as a stage cover in a public park or community space. I was inspired by the pictures under the assignment and decided to make an aesthetically pleasing and functional structure that can be enjoyed by all!
- Firstly I created the boundaries of the stage cover, which consists of curves (arc), spacing between curves, width, and height. I utilized Lunchbox to loft the resulting surface. I then subdivided the surface of the stage cover into a series of rectangular panels, which were selected from the three curves to unveil a geometric pattern. The surface within each of these panels had to be created too.
- Additionally, using division functions on the controlling curves, the quantity of structural ribs and panel subdivisions can be easily modified. UV grid resolution on the surface is adjustable via sliders to control the number of panels.
- Lastly, I used the Grasshopper nodes to sweep along longitudinal and transverse curves of the structure to create beams that follow these curves. Adjustable radii was connected to the section curves profile so that the beams can change in thickness. This is to ensure that the stage cover has structural integrity.
- The parameters that can be used to flex and dynamically change my structure are
- length and space of base curves
- adjustable radius of beams
- number of ribs and panels
- spacing of grid
