3D website design & WebGL development
Interactive 3D websites in Three.js and WebGL, modelled in-house and fast on a phone.

Everything from brief to handover
Kalex Studio designs and builds interactive 3D websites with Three.js, WebGL and GSAP, from our studio in New Delhi, for brands in India, the US and the UK. We model the 3D assets ourselves in Blender, so the product on screen is accurate, and we tune every scene to load fast on a mid-range phone, with a designed fallback where WebGL is not available.
- 01
3D concept & storyboard
Where 3D helps the story and where it does not, agreed as a storyboard before anything is modelled.
- 02
Modelling in Blender
Products, spaces and abstract forms modelled in-house from CAD files or references, with materials matched to the real thing.
- 03
Three.js & WebGL development
Real-time scenes with lighting, materials and camera paths, built into a Next.js site rather than bolted on as an embed.
- 04
Scroll-driven 3D with GSAP
Scenes that rotate, assemble or move as the visitor scrolls, timed to the copy beside them.
- 05
Product viewers & configurators
Turn, zoom and switch colours or finishes in the browser, with AR Quick Look on iPhone from the same model.
- 06
Performance & SEO
Compressed GLB models, scenes that load only when they scroll into view, a fallback for every scene and every word of copy in the server-rendered HTML.

Why most 3D websites disappoint
They take ten seconds to load
Unoptimised models weigh tens of megabytes, and visitors leave before the scene appears.
The 3D is decoration, not the product
3D earns its place when it shows the product or the space better than a photo can.
Search engines see an empty canvas
Copy drawn inside a WebGL canvas is invisible to Google and AI crawlers.
It breaks on half the devices
Older phones and low-power mode get a blank box unless the build plans for them.
How long it takes
- 3D hero scene on an existing site
- 3–5 weeks
- Full 3D website with CMS
- 8–12 weeks
How a project runs
- Week 101
Concept & storyboard
What the 3D has to show and where it sits on each page, sketched as a storyboard and agreed before modelling starts.
- Weeks 2–302
Design in Figma
Desktop and mobile layouts with each 3D moment marked frame by frame, so the scene and the copy are designed together.
- Weeks 3–503
Modelling & look development
Models, materials and lighting in Blender, reviewed as still renders before they go real-time.
- Weeks 5–904
WebGL build
Scenes built in Three.js on a live staging link and tested on real phones from the first week of build.
- Weeks 9–1005
Optimise & launch
Model compression, fallbacks and Core Web Vitals checks, then launch and handover of the code and every source file.
3D websites are quoted on scope. They build on our multi-page website package, which starts from $1,500, and the 3D adds to that depending on how many scenes there are, whether we model the assets or work from your CAD files, and how interactive each scene is. You get a fixed quote after a 20-minute intro call.
Not when it is built for phones first. We compress models with Draco or Meshopt, keep textures small, load each scene only when it scrolls into view and reduce the rendering work on low-power devices. Core Web Vitals are measured on a mid-range Android phone before launch, and a scene that costs too much speed is simplified.
They read everything outside the canvas, which is why we keep headlines, copy, product details and structured data in the server-rendered HTML and use the 3D scene to illustrate them. Nothing a search engine needs lives only inside WebGL.
Spline is quick for simple interactive shapes and fine for a prototype. Three.js gives full control over loading, performance and interaction, which matters on a production site. If the visitor only needs to watch rather than interact, a well-compressed video is lighter than any 3D scene, and we will recommend it.
They get a designed fallback: a still render or a short video of the same scene, next to the same copy. Nobody sees a blank box or a broken page.
Our studio is in Mehrauli, New Delhi, India. We build 3D websites for brands in Delhi NCR, across India and in the US, UK and Europe. Delhi clients can review work with us in person, and every project runs on a live staging link from the first week of build.
