Assignment 0.1 — Digital Gaussen Diagram

Digital Design Methods I | Grasshopper

In this exercise you build a Grasshopper definition that generates the Gaussen climate diagram digitally — first for the city you hand-drew this week, then for the Island of Syros.

Tip: Set the Rhino model units to meters before you begin modeling.

Part A: Data Gathering (1 pt)

Task 01 — Find & format the climatic data

• Find monthly average temperature and precipitation data for your place — (0.5 pt)
• Export it as a correctly structured CSV: one column per variable, one row per month — (0.5 pt)

Part B: Grasshopper Definition (7 pt)

Task 02 — Read the data into Grasshopper

• Use the correct component to read the CSV file — (1 pt)

Task 03 — Extract & organize the data

• Split the data into separate temperature and precipitation lists — (1 pt)

Task 04 — Construct the diagram using the BAL component

• Use the Being Alive Language (BAL) Gaussen diagram component, correctly connecting your parsed data to its inputs, so the curves and axis are generated correctly — (2 pt)

Task 05 — Identify and represent Temperature and Precipitation curves

• Differentiate the curves between the Temperature and Precipitation outputs (linetype, lineweight, color) — (1 pt)

Task 06 — Frame and Label position

• Correctly set the diagram's frame and label (axis units) - (0.5 pt)

Task 07 — Change the diagram's origin position

• Set the diagram's origin to the point (2,10,0) - (1 pt)

Task 08 — Definition runs cleanly

• No errors, reasonably organized and labeled canvas — (0.5 pt)

Part C: Final Output (1 pt)

Task 09 — Diagram correctness

• Both diagrams (your city + Syros) correctly built, axes labeled, months in order — (0.5 pt)

Task 10 — Export

• Export as a PDF: Gaussen diagram in A3 — (0.5 pt)
• Grasshopper script

Bonus (up to +3 pt)

• Color-coded lines — (+0.5 pt): differentiate the precipitation and temperature curves by color instead of linetype.

• Identify and highlight drought period — (+1 pt): Correctly highlight/shade the area where the precipitation curve falls below the temperature curve.

• Create a diagram legend — (+1 pt): Add a clear legend identifying the temperature and precipitation lines.

• File tidiness — (+0.5 pt): clean canvas organization — grouped and labeled components, sensible left-to-right layout, no messy wires.

Deliverables

2 PDFs + 1 Grashopper file + CSV files for each location One PDF per place (your city + Syros), each showing:

• the Gaussen diagram for each place One Grasshopper file with two inputs for csv files

Grading

Each task above is marked complete (✓) (gets all the points) / partially complete (~) (gets half points) / not complete (✕) (no points). The resulting points (out of 9, plus any bonus: max out of 12) converted to ETH 1–6 grading system.
