Course Description

This course explores the role of computation in the conception and representation of form and shape. Learn Python programming language as a creative medium for design, architecture, art and beyond. Learners will develop, analyze and critique algorithmic approaches to digital drawing, modeling, and projection. Specifically, the powerful and robust Python Rhinoscript library will be introduced and explored in detail. This library allows Rhinoceros, the popular 3D graphics and computer-aided design (CAD) modeling software to be scripted with text-based code. Scripting in this manner can automate existing processes and can lead to novel kinds of relationships, and orders of shape and form.

Architects, sculptors, and any artist or designer interested in either fabrication or communication of form and shape will recognize the importance of projection–the the transformation of three-dimensional geometry onto a two-dimensional picture plane, cut sheet, paper, or screen. As a result, this course focuses not only on the generation of geometry, but the output of geometry.

In parallel to extending learners' technical proficiency, this course will touch on the conceptual and theoretical implications of algorithmic design. Each of the five lessons will build upon each other to develop an understanding of the Python language, algorithmic strategies, and digital geometric craft (the interrelated structures and topologies that make up digital models).

Session 1: Procedural Points, Python Basics, and Rhinoscript (November 16, 2018)
Why design algorithmically? Answer this question and learn the basics of Python syntax and organization of the Rhinoscript library in this session. Create, run, and edit your first Python script while learning all about point coordinates and point objects through real-world demonstrations where we'll create procedural point spirals, gradient point clouds, and more.
11 lessons
1. Introduction, Welcome and Resources Available
2. How to Create and Run a Script from Rhino
3. First Python Script: Variables, Math, Code as Sequence of Operations
4. Comments, Calling Functions and the Rhinoscript and Random Libraries
5. Algorithm for Automation: A Counting Loop
6. Conditional Statements and Logic Equations
7. Incorporating Geometric Parameters With Conditions and Loops
8. Logical Adjustments to Loop Algorithm (Premium Exclusive)
9. High-res Image Output and Project Advice (Premium Exclusive)
10. What Lies Ahead, Example Images
11. Reflecting on this Session
Session 2: Curves vs. Curvature (November 23, 2018)
What is the nature of a curve? In this session you'll learn multiple methods for creating and editing curves. You'll also explore concepts such as the “blip”, and the capacity of a set of curves to collectively define space. Example tutorials will show you how to create interpolated curves of various degrees before and after sorting; best fit circles; curve parameters, evaluating curves, and extraction of curve points for the purse of editing curves with looping.
11 lessons
1. A Deeper Dive into Python Random Library
2. Random Seeds and Other Random Functions
3. Lists and Touples in Preparation for Rhinoscript Curve Functions
4. Using a “for” Loop to Step Through Lists, Element by Element
5. Creating Simple Curve Objects with Random Values Using “addInterpCurve” Function
6. Nesting Loops to Create Many Curves with Random Values (Premium Exclusive)
7. Creating Functions: Curves Within a Volume and Flat Curves
8. Two “Blip” Strategies
9. A Third “Blip” Strategy: Modifying a Curve After Creation (Premium Exclusive)
10. Exporting Perspective Image to Adobe Illustrator for Formatting (Premium Exclusive)
11. Session Two Conclusion
Session 3: The Depth Of A Surface (November 30, 2018)
What is the nature of a surface? In this session you'll learn techniques for creating and editing surfaces beginning with the Rhinoscript functions that correspond with the most commonly used surface tools in Rhinoceros: loft, sweep1 and networksurface. Example tutorials will go into lofting and list-management and rebuilding surfaces in sequence.
7 lessons
1. Who is the “User” and Why Would we Program for the “User” in Mind?
2. Using “GetObjects” Function to Incorporate User Input; Extruding Curves
3. Extrude Curves to Create Consistent Surface Areas
4. Comparing Curves from Two Sets for Lofting and Checking User Input (Premium Exclusive)
5. Using “zip” Sorting to Find the “Best” Match between Curves and Target Points
6. Algorithmic Strategy: Adjust Until Geometric Condition Met, Creating a Striated Surface (Premium Exclusive)
7. Session 3 Conclusion, Advice for Project
Session 4: Deconstruction Of Surfaces, The Genesis Of Lines (December 7, 2018)
How can a surface generate lines? How can lines represent a surface? This session begins with an important premise: a surface is a 2-D space organized in terms of 'U' and 'V' axes that can be treated similarly to 'X' and 'Y' axes in Cartesian space. This allows drawing “in” a surface, trimming a surface based on U/V domains and the evaluation of surfaces based on 2-D parameters. Demonstration: Growing lines based on surface normals; surface to surface lines.
10 lessons
1. Session Overview: The Nature of Digital Surfaces
2. Primacy of Lines: Learning from Engraving and Cartography
3. Thinking of Surfaces as 2-D Space, Functions for Evaluating Surfaces
4. Evaluating Surface using U and V Coordinates
5. Constructing a Grid on a Surface
6. Curves at Surface Normal, aka Porcupine Surface
7. Recursive Algorithms and the Design of a Tree Function (Premium Exclusive)
8. Roaming Lines, Random Paths Along a Surface (Premium Exclusive)
9. Note About Assignment: Export Vector Formats for Editing
10. Conclusion: Authorship and Creativity
Session 5: The Project Of Projection (December 14, 2018)
How can projection serve as a creative act? In this session you'll explore methods for geometrically constructing perspective computationally and use projective methods for the creation of new forms and shapes. Example tutorials will include constructing a set of perspectives using surface-plane intersection.
9 lessons
1. Re-framing the Term, “Representation”

What You Need to Take This Course

Students should be comfortable with Rhinoceros modeling software. No computer programming knowledge is required, though students who are proficient in another programming language or have dabbled in Python will find most of the content new and useful.

  • Software:
    • Rhinoceros modeling software (latest build, version 5.x) is required with either an education or professional license on either Mac or Windows operating system.
    • If using Mac OS, an external text editor is required.
    • A programming-specific text editor is recommended: Komodo Edit or SublimeText are excellent options.
    • Rhinoceros is packaged with Iron Python automatically. No additional installation of Python is required.
