Interactive 3D web experiences built for real-world performance
Causal Labs builds premium, performant 3D web experiences — React Three Fiber, three.js, GSAP and WebGL — engineered to hold 60fps and degrade gracefully across devices, not just look good in a demo reel. This site's own scroll-driven visual system is a live example of the approach.

Why most 3D web projects feel great on a demo machine and terrible in the field
The gap between a 3D web portfolio piece and a production site is almost always device coverage: what runs smoothly on a developer's desktop GPU frequently drops frames or fails to load entirely on a mid-range phone. A 3D web build needs a genuine reduced-motion and low-power fallback tier from day one, not as an afterthought.
How we approach an interactive 3D engagement
Design
We define the fallback tiers upfront — full WebGL, reduced-motion, and no-WebGL — as part of the design, not a later patch.
Build
React Three Fiber / three.js scene construction with performance budgets enforced from the first commit.
QA & review
Tested across real low-end and mid-range devices, not just the development machine.
What's included
Performance-budgeted 3D scenes
Built against a frame-rate and load-time budget from the start, not optimized as an afterthought.
Graceful degradation
Reduced-motion and no-WebGL fallback tiers that keep the page usable and on-brand on any device.
Scroll-driven motion
GSAP-choreographed interaction that resolves with the content rather than competing with it.
Cross-device testing
Verified on real mid-range and low-power devices, not just a development workstation.
- Production 3D scene(s)
- Reduced-motion and no-WebGL fallback tiers
- Performance budget documentation
- Cross-device test results
The primary framework for declarative, component-based 3D scenes in React.
The underlying WebGL engine R3F is built on.
Drives scroll-linked and choreographed motion around the 3D scene.
The rendering technology powering the 3D layer, with defined fallbacks where it isn't supported.
Built immersive React Three Fiber experiences and a video-composition framework with scroll-driven 3D and postprocessing.

Questions about this service
Will a 3D site actually work well on mobile?
Only if the fallback tiers are designed in from the start — which is how we build it. A full WebGL experience on desktop, a lighter or static experience on mobile/low-power devices, by design rather than by degradation.
