Assignment 03

Overview

This assignment will mainly focus on what you've learned in the lecture -- "Data Tree" in Grasshopper. After this assignment, you should become more comfortable with operating complex data structures (list, tree, list + tree) and apply it to your daily tasks.

This assignment may seem challenging at the beginning, but are the advanced basics for working with Grasshopper.

Part A: Line Connection (8pts)

For this task, you're given two sets of points with the same number $N$ (can be adjusted by a single slider). Your task is to connect lines between the two set of points (independent task):

Task 01

1. Connect lines between the two points with the same corresponding index ($0-0,1-1,\cdots$).
   • Final # of lines: $N$.
2. Connect lines between the two points with the same sum of corresponding index (if total 10 points, then $0-9,1-8,\cdots$).
   • Final # of lines: $N$.
3. Connect lines between every point in set A with every point in set B.
   • Final # of lines: $N\times N$.
4. Connect lines between every point in set A with every point in set B except the one with the same index.
   • Final # of lines: $N\times (N-1)$.

Task 02

1. Connect lines between every point in set A (except for the FIRST and LAST point) with every point in set B.
   • Final # of lines: $N\times (N-2)$.
2. Connect lines between the corresponding points with "odd index" in set A and "even index" in set B.
   • Final # of lines: $\frac{N}{2}$.
3. Connect lines between every points with "odd index" in set A and "even index" in set B.
   • Final # of lines: $\frac{N}{2}\times \frac{N}{2}$.

Task 03

1. For each of the points in set A, connect a line to the points in set B with indices: $i_B<=0.5\cdot i_A$ (For instance, the point with index 6 in set A should connect to points with index 0-3 in set B).
2. Find a set of points ($N-1$) for each of the neighbouring two points in set A (here, we label them as set C). Merge these points with set A into one same data stream, and connect lines with points in set B so that:
   1. (optional, only for visual clearance) move set C higher/lower so that the points locate in a different height than set A;
   2. use only ONE one component for the line creation;
   3. each of the points from set A and C will connect a line to the same index in set B (result should be similar as Task01-1);
3. Similar to the above task (03-2), but with the requirement:
   1. use only use ONE component for the line creation;
   2. points from set C with ODD index will connect lines to all the points in set B (result should be similar as Task01-3);
   3. points from set C with EVEN index will connect lines to all the points except the point with the same index in set B (similar to as Task01-4);

Part B Topography (6pts)

For this task, you will use the result of "Part A: Task 01-1" as the starting point, and build a topography after completing all the tasks below.

Task 01

1. Divide the $N$ lines into a series of points with a decent resolution ($n>15$). Apply a "sine" or "cosine" function to the allevation (z-component) of those points.
2. Connect the modified points into $N$ curves.
3. Loft the curves into a continuous surface.

Task 02

1. Repeat Task 01, with the additional requirement:
   • The START and END points of each curve are at the extremum locations -- they are located to the highest/lowest possible location of the "sine" or "cosine" function.
2. Connect the modified points into $N$ curves.
3. Loft the curves into a continuous surface.

Task 03

1. Repeat Task 01, with the additional requirement:
   • One of the peaks of the "sine" / "cosine" wave should appear at the diagnal line of the topology (illustration below).
2. Connect the modified points into $N$ curves.
3. Loft the curves into a continuous surface.

Part C: Soil Diagram with BAL (6pts)

You've learned how to use BeingAliveLanguage to draw soil diagrams. For this part of the assignment, you're asked to draw a soil diagram with multiple horizons with the provided soil data.

You need to submit a exported .pdf format drawing containing the following content:

• One soil profile diagram with multiple soil horizons
• For each horizon, label the corresponding soil type
• For each horizon, label the corresponding depth of each horizon inside the soil
