Interactive 3D Hero Section on Your Existing Site

Most focused upgrade — keep the existing site, replace just the hero with a real WebGL scene that reacts to scroll and hover.

The most common request I receive: "we have a site that works, but the hero doesn't pull its weight". An interactive 3D hero is a focused intervention — the existing WordPress, Shopify, or custom site keeps everything else, only the first 100vh becomes a WebGL scene. Pricing \$1,500-\$2,500, delivered in 2-3 weeks. Technical scope: one JS module loaded lazy, one CSS file, glTF asset budget under 800KB. The existing site's SEO stays intact, mobile tests still pass, only the first impression changes — but that's the impression that matters.

Concrete deliverable

What you receive at handover: a working Interactive 3D Hero Section on Your Existing Site on production hosting, all source files committed to your GitHub repo, og-images for social sharing, basic schema.org markup, sitemap entry, and a 5-min walkthrough video. The site is yours from day one — I never hold code hostage.

Engagement model

Fixed price, fixed deadline, payment on delivery. The price covers up to two rounds of revision within original scope. Out-of-scope changes are quoted separately before any work happens. No retainer required, no monthly minimum. We agree once, I deliver, you pay.

Technical foundation

Stack: Three.js v0.170 with GSAP for animation timeline, Lenis for smooth scroll, Vite for build, GLSL for custom shaders when needed. Hosting on a Hetzner / DigitalOcean equivalent — fast first byte, HTTP/2, Brotli compression, CDN for static assets. Lighthouse mobile 85+ guaranteed.

Where it fits

This service is the right call when the brand needs a visual moment that ranks beyond the average competitor — agencies pitching new business, premium e-commerce, portfolios that need to look ahead-of-curve. If you need a basic content site or blog, a static-site generator without 3D is more economical and ranks just as well for simple keyword targets.

Frequently asked questions

Do you write technical documentation in English?

Yes. All deliverables — code comments, README, technical handoff doc, walkthrough video — are in clean professional English. The site itself can be in any language; content is your responsibility, code and docs are mine and they're English by default.

How does payment work for non-EU clients?

USD wire transfer or USDC stablecoin. Formal invoices from a registered Serbian sole-proprietor, accepted under most reseller-of-record platforms (Deel, Remote, Ontop). For US clients I also support W-8BEN-E if the relationship requires it.

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.
