Modeling Approach:

• For Part 1, I closely followed the assignment instructions to ensure that I created an arc-shaped curve with adjustable parameters. I then extruded the arc to an adjustable height, and discretized the surface into a grid of squares that can be parametrically sized. To ensure that each grid surface panel maintained a square shape, I created a number slider for discretizing the height of the extrusion and then found the length of each segment. I divided the arc length at the base by the computed segment lengths and then rounded that number to the nearest integer to determine the number of segments to discretize the base arc into. Next, I created the grid and mapped my image onto it using the image sampler component in Grasshopper. To ensure the final image was rotated, I performed an operation to the uv coordinates by replacing u with 1-v and v with u prior to feeding into the image sampler.
• For Part 2, I first drew a line with parametric length on the base plane. To turn it into a sin curve with adjustable parameters, I used the expression tool to formulate my equation with inputs for each equation parameter. I used the Lunchbox panel component to create a grid of rectangular panels, where I set the lengths of each subdivisions initially to meet the 4”x8” panel size requirements. I rotated the image the same way as in part 1. To sample the image color data to determine the height of the extruded panels, I used the text split component to get rid of the comma delimiters and then performed mass addition of the values. To make sure that the extrusions were not too dramatic, I multiplied them by a small factor before setting the extrusion heights.
