Discipline Specification // 3D INTERACTIVE WEBSITES

3D & Interactive Website Development

A 3D website built by someone who understands the medium is different from one assembled from a template. Scroll-driven camera movement, geometry that responds to user input, shader materials that shift with scroll position — these are things that require knowing Three.js and GSAP at a mechanical level, not just knowing that they exist. SynS Infrastructure uses React Three Fiber for the 3D layer, GSAP ScrollTrigger for the timeline, and Lenis for smooth scroll — the current production-standard combination for web 3D. Performance is not negotiable: GLTF models compressed with Draco, bundle-split so the 3D runtime never loads on pages that don't need it, and `prefers-reduced-motion` respected throughout.

LOADING 3D ENGINE...
Target Alignment

Who this is for

  • 01A startup founder who wants a landing page that makes investors and customers stop scrolling — not another gradient + hero image.
  • 02A creative studio or agency looking for a technical partner to build the 3D interaction layer they've designed.
  • 03A product that has a physical or spatial component (hardware, architecture, real estate, manufacturing) that would benefit from a 3D representation.
Deliverable Scope

What's included

  • ✓3D scene built with React Three Fiber — written as React components, not raw Three.js imperatives
  • ✓Scroll-driven animation choreography via GSAP ScrollTrigger — camera moves, scene transitions, reveal animations
  • ✓Smooth scroll with Lenis — the detail that makes motion feel deliberate rather than janky
  • ✓3D models in GLTF format, Draco-compressed for the web — not OBJ, not uncompressed
  • ✓Bundle isolation: Three.js and R3F only load on the page that needs them (Next.js `dynamic` with `ssr: false`)
  • ✓Fallback for `prefers-reduced-motion` — static presentation without animations for users who need it
  • ✓Performance budget maintained: target 95+ Lighthouse performance score
Engineering Stack

Stack & tooling architecture for 3D & Interactive Website Development.

Why we choose each component in the production runtime.

React Three Fiber

3D in React component model — composable, typed, fits Next.js natively

drei

R3F helper library — cameras, loaders, controls without hand-rolling

GSAP + ScrollTrigger

The industry standard for scroll-timeline choreography. Owns the animation timeline, R3F owns the render.

Lenis

Smooth scroll layer (~3KB). Lerp value kept between 0.05-0.15 for native-feeling scroll without INP regression.

Three.js

The underlying 3D engine — used through R3F, not directly in most cases

Engagement Protocol

How this discipline executes.

01

Scope & Architecture

Define exactly what gets built, what doesn't, and milestone criteria — in writing, before work starts.

02

Iterative Staging

Weekly written updates with staging deployments from the first sprint. Test features as they are built.

03

Handover & Ownership

100% repository, credentials, and documentation handed over. Retainers available for ongoing evolution.

Technical Clarifications

Questions & answers for this discipline.

Will this work on mobile?+

Yes, with appropriate fallbacks. 3D at full fidelity on a phone is expensive. We design mobile experiences that preserve the visual intent — simplified geometry, reduced particle counts, maintained performance budget.

How does this affect page load speed?+

Three.js is a large runtime. We code-split it so it never loads on pages that don't need it, compress all 3D assets with Draco, and lazy-load below the fold where possible. The goal is 95+ Lighthouse performance — not 70 with a disclaimer.

Can you work from a Figma file or motion brief?+

Yes — a motion brief or storyboard is the ideal starting point. If you have a Figma design, we can build from it. If you have a concept but no file, the scoping session covers what the motion should communicate before we decide how.

Do you provide the 3D models or do we supply them?+

Either works. If you have models, they'll be optimised for the web. If you don't, we'll source or create appropriate assets — and be explicit about what that costs.
