Free Mini Workshops in Paris
Three free two-hour mini workshops with Spline, fal.ai and Miris in Paris on September 9, 2026. Included with a Three.js Conf ticket, 50 seats each.
ADVANCED R3F: 2-Day Intensive
September 8 & 9 at Gobelins, Paris.
Two days of advanced React Three Fiber with the core pmndrs team who build and maintain it - all about the techniques and performance habits that turn a demo into something you can ship.
Workshop instructors
What you will learn
Architect scenes that scale
The patterns the maintainers actually use - component design, state management and reconciler internals that keep large scenes maintainable, not fragile.
Make it fast, and keep it fast
Techniques that hold a heavy scene at a steady 120fps on real devices, not just your laptop:
- WebGPU: the modern rendering path, and when it's worth the jump from WebGL.
- Instancing & draw-call batching: turning thousands of objects into a handful of calls.
- Compute shaders: moving heavy per-frame work off the CPU and onto the GPU.
- Memory budgets & profiling: the workflow that catches regressions before they ship.
What we bring
No setup friction - focus entirely on creating:
- Production-ready repos: pre-configured official repos, ready to go.
- Per-attendee guides: step-by-step documentation for every milestone.
- Fail-safe support: instructors on hand plus a setup fallback plan - no one gets stranded.
The maintainers who build this
Kris maintains React Three Fiber and has spoken on hitting 120fps in React. Dennis led the R3F v10 release and builds its WebGPU tooling. Learn from the people who built it, not performance theory.
Human size
Capped at 30 on purpose - hands-on, every question answered, momentum instead of a backlog of notes.
