Tessellation with point grids for Quads and Triangular tiles.

January 6th / 7th / 8th / 9th 2026, 10:00 to 13:30 hs.
4-day training course (in-person) teaching you the basics in tessellation
of surfaces, and how to work with lists in Grasshopper.

We will look closely at:

Point grids (set up by coordinates, or extract them from surface).
Applying rules to tessellate a surface (planar or cylindrical).

We will look at case studies:

Gridshell Roof of the British Museum (completed 1999, London, Foster &

Partners).

30 St. Mary Axe - a.k.a. The "Gherkin" (completed 2004, London, Foster

& Partners).

The focus will be on using Grasshopper for exploring tessellation and related concepts of
architectural geometry. Nonetheless, we will also have a feel for Structural Design (following
the concepts explored in the Karamba3D course in November 2025 at UCL The Bartlett).

What will you learn?

Setting up point grids by coordinates ("construct point") using lists ("graft" and "flatten").
Implementing mathematical tools ("series" and fundamental trigonometry concepts) to create points in a harmonic distribution.
Reconstructing a surface with a harmonic grid of points (Extracting points from custom "messy" curves or "messy" surfaces).
Setting up orthogonal correspondence of lines within a harmonic grid of points (Quads).
Setting up diagonal correspondence of lines within a harmonic grid of points (Triangular tiles).

This will be a class maximum of 4 students. Please feel free to drop me an email at eugeniavil@gmail.com and I will reply to you with more info about the course.

Best wishes, Maria
