Modeling a Parametric Structure:
My modeling process involved first generating a sketch of what I wanted the model to look like and how it could potentially change to allow for the parametric integration. I then started by modeling the roof aspects of the structure, added in the beams. and lastly added in the columns. I adjusted these variables as needed to ensure they could adapt with the remainder of the structure. This structure is essentially an adjustable curved roof with 4 exterior columns supporting it. There are additionally beams placed along the length of the roof which also contribute to controlling the geometry. The parameters that can be adjusted include the length of the structure, the number of beams, the control points of the roof structure, the base height of the structure, and the width of the structure. The number of panels can also be adjusted longitudinally and transversely.
Transforming your Geometry:
For the second stage, I replaced the curve defining the roof geometry with a sine curve and additional parameters defining the curvature and amplification of this curve. A majority of the remaining model remained unchanged, besides the parameter for adjusting the beam numbers which was implemented into the angle generation part of the new sine curve. With the minimization of these parameters, a very small structure is created, or, if the beam number is increased, a flat roof structure is made. When maximizing the values, particularly the curvature, a very odd shape is made and the longitudinal segments of the panel need to be increased to ensure the surface’s edges are not too sharp. The curvature and amplification can take negative values, which ends up producing a mirror image of the original behavior. For example, the curve can become more convex than concave.
