Interactive 3D is one of the fastest ways to make a technology brand feel premium — and one of the fastest ways to make a site feel broken. The difference is entirely in the engineering discipline around it.
Our rule is simple: motion must earn its place, and it must never delay access to the message.
Budget the experience before you build it
A 3D hero competes with everything else on the page for bandwidth, memory and main-thread time. Set budgets up front:
- Compress models (Draco / Meshopt) and target a small hero payload.
- Cap the device pixel ratio; more pixels are rarely worth the cost.
- Lazy-load the scene and pause the canvas when it scrolls off-screen.
- Dispose of geometries, materials and textures you no longer need.
Design for tiers, not for your laptop
The device that renders your demo beautifully is not the device most visitors use. We ship quality tiers:
- High — full model, post-processing, particles, pointer response.
- Medium — reduced geometry, lower DPR, limited effects.
- Low — a crisp static image, no continuous canvas at all.
Detect capability, then serve the right tier. Nobody should get a stuttering hero to prove a point.
Respect reduced motion — and mean it
prefers-reduced-motion is not a nice-to-have. When it is set we disable smooth
scrolling and camera travel, replace scroll-scrub with simple fades, and show a
static or gently rotating visual. The content is always immediately available.
Keep the message readable without the 3D
The core value proposition — who you are and what you do — must land even if WebGL never initializes. The 3D object is an amplifier, not a dependency. It carries a text equivalent for screen readers and never gates understanding.
A premium 3D experience and a fast, accessible site are not a trade-off. They are the same engineering problem, solved on purpose.
This is exactly how the site you are reading was built. If you want an experience that feels cinematic and scores well, let's talk.
