1. A Walk in the Park

Overview & Modeling Approach: This model explores terraced topography to create a dynamic, human-scale ground surface for a park. Using Dynamo, I generated a 200’ x 200’ rectangular grid of cuboids. I then introduced an attractor point and utilized a sine wave function to adjust the height of each cuboid based on its distance from that point. To ensure the cuboids sat properly on the ground plane, I calculated the required Z-translation for each so that all their bases rest uniformly at the same base elevation.

2. Eliminate the Echo

Overview & Modeling Approach: This model designs an undulating, sound-dampening ceiling system, simulating an application for a space like a recording studio. Using Grasshopper, I established a base ceiling plane at a height of 12 feet and populated it with a rectangular grid of cylinders. By applying attractor logic, the distance from the attractor point to each cylinder dictates its Z-axis scale. I evaluated the distances, converted them to radians, and ran them through a sine function, scaling the cylinders downward in a rippling wave pattern while ensuring all lengths remained positive.
