Three.js / React Three Fiber
3D in the browser that stays with you.
Three.js and React Three Fiber bring true 3D straight into the browser – no plugin, no download. Products can be shown from every angle, spaces made walkable, and motion created that a flat page could never achieve. It is the technology behind many award-winning web experiences.
How Conexa Digital uses it
At Conexa Digital we use Three.js and React Three Fiber where a site should visibly stand apart from the crowd – a rotatable product view, a spatial landing page, or an interactive scene that tells a story. Whether the tool fits a given case is a decision we make together, measured against the goal: it is a capability in our toolkit, not a standard we impose on everyone. Where simpler means suffice, we use them.
What we use it for
Why it matters to you
A 3D experience that runs the moment someone opens the page stays in memory and invites them to linger – exactly what turns attention into interest. What matters is that it runs just as cleanly on an ageing laptop as on a new machine. That is why we always build a lighter fallback, so no one is left staring at a stuttering or empty page.
In practice
A manufacturer wants to show a product that can be explored from every angle, say a piece of furniture with several colour and material variants. A photo carousel only ever shows fixed, predetermined views. With Three.js and React Three Fiber we instead build a model that visitors can rotate freely by mouse or finger and view from any perspective. This reveals details that would stay hidden in a catalogue photo — the back, a seam, or how a fabric behaves in the light. So that the page remains usable on an older device too, we provide a simpler view as a fallback in case the 3D rendering would be too heavy there.
When we do not use it
Three.js and React Three Fiber are the wrong choice for most ordinary subpages — a services overview, a contact page or a blog article needs no 3D; that only piles on unnecessary computing power and load time. Heavy 3D scenes noticeably burden load time and therefore do not belong on every page, but deliberately where they serve a clear purpose. On text-heavy or information-driven pages we rely instead on clear layout, typography and simple imagery, because visitors there want to get to the content quickly, not to a spectacle.
Frequently asked questions
What is the difference between Three.js and React Three Fiber?
Three.js is the underlying 3D library for the browser. React Three Fiber is a layer on top that integrates it into modern React websites. In practice the two are used together to embed 3D scenes into a site in a maintainable way.
Does 3D in the browser run on weaker devices and smartphones?
In principle yes, but it depends on the implementation. We detect device capability and serve a lighter rendering on weaker hardware instead of forcing an overloaded scene. That keeps the page usable everywhere.
Does every website need 3D?
No. 3D pays off when it serves a clear purpose – making a product tangible, for instance. Where it would only be dead weight, Conexa Digital will openly advise against it and choose a better-suited approach.
