Tres — Three.js for Vue 3

Tres (tresjs.org) is the Vue 3 equivalent of React Three Fiber — declarative 3D web in Vue's composition API.

Tres (tresjs.org) brings declarative Three.js to Vue 3. For Vue/Nuxt projects with 3D needs, Tres is the natural fit — same component-driven mental model as the rest of your Vue app. Active development, growing ecosystem, similar in spirit to React Three Fiber. Use cases: marketing sites built on Nuxt, dashboards with interactive 3D visualizations, Vue-based portfolios with 3D scenes. For new Vue 3 projects with 3D, default to Tres. For projects on Vue 2, Tres doesn't support it — you'd migrate to Vue 3 first or stick with vanilla Three.js. I take on Tres projects when clients are on Nuxt; default to Three.js or R3F otherwise.

Performance budget

Lighthouse mobile target: 85+ across all categories. I measure on real devices, not just emulator. Asset compression: glTF + Draco for meshes, KTX2 for textures, Brotli for shaders. Lazy-load any tres vue three js scene that isn't above the fold so the first paint stays under 1.5s.

When this is overkill

If the goal is a simple e-commerce listing or content blog, a full tres vue three js setup is overkill — a CSS-driven hero plus static images converts just as well at 1/10 the cost. tres vue three js earns its keep when the brand needs a memorable visual moment or when 3D actually clarifies the product (configurators, tours, demos).

What you get hands-off

After delivery: source repository on GitHub (private), commented code, a 5-min Loom walkthrough explaining the scene logic, and the asset pipeline documented. First year of hosting and minor revisions is included. After that we agree on a maintenance plan if needed.

What this delivers

Concrete output: a working tres vue three js integration on a real production site, not a demo. The integration includes device-tier detection so weak phones get a lighter version automatically. Source files are handed over in their original formats — Blender, GLSL, glTF — so any future developer can continue where I stopped.

Frequently asked questions

Why pick this technology over alternatives?

It has the largest production-quality ecosystem, the most documentation, and the most experienced developers available. For a site you want to maintain for 3+ years, ecosystem maturity matters more than feature peak.

What if a newer tool comes out next year?

I track new tooling and migrate when it makes sense, but only after the new tool ships stable production releases for at least 6-9 months. I don't rebuild client sites on bleeding-edge tools — that's the path to broken sites.

How long does this take?

Standard scope: 4-6 weeks from contract signature to live site. Larger scope (configurator, multi-scene scrollytelling) takes 8-12 weeks. Rush projects (2-3 weeks) are accepted with a 30-40% rush surcharge.

What does it cost?

Hero-section 3D upgrade: \$1,500-\$2,500. Full multi-scene 3D site: \$3,500-\$8,000. Configurator with custom shaders: \$5,000-\$12,000. All fixed-price, source code included. EUR equivalents on request.

What if my visitors are on weak phones?

The site detects device tier before the first scene loads and serves a lighter version on weak hardware (fewer particles, simpler shaders). Devices without WebGL get a static fallback that preserves the visual language and conversion path.
