Walk in the Park
In this assignment, I designed a park with multiple walkways for pedestrians and a small hill where children can play and have fun. The hill is intentionally kept low so that people on the walkways can still see each other, making the space feel more open and less confined. I placed the attractor point at (0,0) to create a more noticeable sine wave effect across the park. Starting with a 200’ × 200’ grid, I then adjusted different parameters such as the base height, amplitude, and number of waves to shape the overall terrain. I also adjust the cuboid’s width and length to match the grid spacing.
Eliminate the Echo
In this assignment, I designed a series of tubes for an auditorium ceiling to help reduce echo. To improve the acoustic performance, I shaped the tubes using a sine wave pattern, and placed the attractor point at the center of the ceiling to create a more visually balanced and aesthetic effect. I also noticed that when I used the centroid of each grid cell as the base of the cylinders (as shown in the figure below), the cylinders were positioned at the center of the grid instead of the corners. This change not only altered the overall wave pattern but also produced a different visual effect, which I think offers an interesting alternative design.
Building on this, I created an XY plane and moved it up to 12’ to represent the ceiling, then generated a rectangular grid and placed cylinders at each grid point with a defined radius and initial height. The height of each cylinder was controlled based on its distance to the attractor point: the distances were remapped according to the desired number of waves, converted to radians, and passed through a sine function to create a smooth ripple effect. By adjusting parameters such as amplitude and base height, I was able to refine the final form, and then scaled the cylinders in the Z direction to complete the design while hiding the original geometry for a cleaner visualization.
