Thousands have seen Alexandr “Sasha” Trubetskoy’s maps. But not everyone knows the internet-famous cartographer is only 20 and recently wrapped up his sophomore year of college.

Trubetskoy, whose most recent map turned ancient Roman roads into a modern subway map, shares his data visualizations and cartographic musings on his personal website and across numerous subreddits dedicated to data visualization.

A tour of #Voronoi tessellations - I love these diagrams. There is lots you might already know - but I discovered the #3D method of rendering them: much more elegant than brute force and much simpler to understand than Fortune’s algorithm.

Let’s draw a coastline – Fantasy Maps for fun and glory

We already got scalable Voronoi graph and heightmap on it. The next step is to draw a coastline that will make the border between water a land masses clearer.

Les posts récents (#voronoi) sur les réseaux cellulaires m’ont refait penser à ▻http://n-e-r-v-o-u-s.com

Ils fabriquent des trucs (bijoux, lampes, puzzles) en utilisant des méthodes génératives (et #impression_3D) s’inspirant de la nature.
On peut parfois faire ses propres pièces avec un configurateur.

Our work at Nervous System combines scientific research, computer graphics, mathematics, and digital fabrication to explore a new paradigm of product design and manufacture. Instead of designing objects, we craft computational systems that result in a myriad of distinct creations. These forms are realized using computer-controlled manufacturing techniques such as 3D printing, laser cutting, and CNC routing.

Here we explore what our favourite javascript library, #d3.js, allows to do with #Voronoi diagrams.

transmote [v4] : dividing space - Eric Socolofsky.

Understanding geometry doesn’t require pen, paper, and textbooks. Another way to learn geometry is to experience it and experiment with it. This is the philosophy behind the Exploratorium’s “Geometry Playground” exhibition.

Dividing Space presents an interactive Voronoi diagram – visitors can manipulate the diagram by configuring a field of red pegs and sending a blue puck through them. Custom software ties into a computer vision system to enable this realtime, playful interaction with otherwise complex geometry.

“These are some notes on how I generate the maps [...] I wanted to make maps that look like something you’d find at the back of one of the cheap paperback #fantasy novels of my youth.”

World Airports Voronoi

Each region consists of the points that are closer to a particular airport than any other. This partitioning of the sphere is called a spherical Voronoi diagram, and was calculated by d3.geo.voronoi, which is currently under development.
