Three.js Conf
The first Three.js conference took place in Paris.
Three.js has been running 3D in browsers for years without ever having its own conference. In 2026, creative developer David Ronai gathered the community at the Maison de la Chimie, on 10 and 11 September, with the first public appearance of Mr.doob, the library’s creator, as its high point. Hervé shaped the identity of the event and rolled it out across the website, social media, on-site materials and goodies.
Context
Three.js is a JavaScript library for creating 3D scenes in web browsers, a technology widely used in interactive design.To celebrate its use and bring the community together, creative developer David Ronai decided to organize the very first Three.js conference.
Hervé supported the entire organization by creating the event's branding, the website, and all printed and digital communications, bringing Three.js technology into every step. Like the teaser below, for example.
Step one
First, and fast, we had to find a concept strong enough to carry the conference's entire art direction.We explored several directions as low-fidelity wireframes, starting from two angles: Three.js itself and the community around it.
Step two
This direction led us to explore different ways of representing the audience and the community.
The one we chose felt the most inclusive: simple spheres for the characters, but with a wide range of textures and expressions. This way, every character is equal, yet incredibly diverse.
A one-of-a-kind look
Every attendee leaves with a unique avatar, generated on the fly. With a single click on "Randomize look", the sphere gets a new skin: iridescent textures, color gradients, grain and reflections recombine to give birth to a new creature, never quite the same.
Express yourself!
Eyes and expressions vary too, so everyone can find a character that looks like them or makes them smile. A rich set of combinations makes every avatar unique, while keeping a graphic consistency that makes the family instantly recognizable.
Handmade hardware
We loved pushing the conference sphere off the web and turning it into a little character you carry around, a bit like a Tamagotchi. The result: 40 handmade badges that come to life and recognize each other.
The identity at full scale
Dressing the venue was the final step in developing the visual identity. To get a better feel for the result, Misaki Kitano (co-organizer) used AI to create a 3D map of the Maison de la Chimie, so we could test all our designs to scale.
