Designing 3D experiences on the web
Real-time 3D in the browser is no longer a feat: it's a medium. How to design immersive worlds without sacrificing performance or accessibility.

The browser has become a 3D console. With no install, from a plain link, you can now walk through a gallery, configure a product or explore data in volume. But you have to design for the web, not despite it.
Real time changes the rules
A 3D film computes each frame over hours. The web has 16 milliseconds per frame. That constraint isn’t a handicap: it’s the grammar of the medium. It forces sharp choices, and rewards technical elegance.
Designing within a budget
A 3D scene is designed like a budget you allocate:
- Geometry: favor lean meshes, sculpted where the eye lands.
- Textures: compressed, atlased, resolution matched to distance.
- Light: precomputed when static, dynamic only where it’s perceived.
The beauty of a real-time scene comes not from its complexity, but from the precision of its spending.
Immersion excludes no one
An exceptional 3D experience always plans its alternative: a 2D fallback,
keyboard navigation, respect for prefers-reduced-motion. Technical prowess only
has value if it stays hospitable.
That’s where the difference is made between a demo that impresses and an artifact you actually use.
