I'm Shashikant Shah, a web developer and digital marketing expert in Kathmandu. I build the 3D scenes and the motion on this site myself, and this page is about doing the same for yours: when it is worth it, how I keep it fast, and what it costs.

Short answer: 3D website design means real time scenes rendered in the browser: a product you can turn around, a hero that answers the cursor, a diagram that builds itself as you read. It earns its place when it shows something words and photos can't. It fails when it is decoration that costs three seconds of load time on a phone. I design for the first case and refuse the second.

When 3D earns its place, and when it does not

Use 3D when the thing you sell is physical and people want to look at it from every side, when a service is easier to show than to describe, or when the brand sells on feel and a flat template would undersell it. A furniture maker, a trekking agency with a route to show, a software product with an interface worth animating: all good reasons.

Don't use it as wallpaper. A spinning shape behind the headline tells a visitor nothing and costs them data. If your pages exist to answer a search and get a phone call, as most Nepali business sites do, the budget is better spent on the copy and the speed. I'll say which case you are in on the first call, and I lose the project when the answer is that you don't need it.

What I build

  • Three.js and WebGL scenes. Lit, shaded objects rendered live in the browser, from a single product to a full environment, with the camera and the lighting tuned for the page they sit on.
  • Product viewers. Turn, zoom and switch finishes on a real model of what you sell, loaded only when the visitor asks for it.
  • Hero scenes. A scene that reacts to the pointer or to scrolling, placed behind or beside the headline, with the headline readable before the scene arrives.
  • Diagram and process scenes. A pipeline that builds step by step, a map that draws its routes, a stack that assembles: the kind of scene that explains a service in five seconds. The service pages on this site use them.
  • Motion without 3D. Scroll linked reveals, counters and transitions with GSAP where a 3D scene would be too much. Often this is the right amount of motion.

The performance budget comes first

Every 3D page I ship meets the same rules, and I write them into the quote.

  • The page is readable and usable before any 3D loads. The scene starts after the first interaction or a short delay, never in the critical path.
  • Text in the scene also exists as real HTML, so Google and the AI crawlers read it and screen readers announce it.
  • A visitor who has asked their phone for reduced motion gets a still image or a single frame.
  • I compress and size the models and textures for mobile data, with a fallback when WebGL is missing.
  • Core Web Vitals stay green. If the scene costs the page its speed, the scene changes, not the budget.

This site is the proof: the homepage hero loads its Three.js scene after the page is usable, every service page scene ships with a written fallback, and each deploy runs speed and layout checks before it goes live.

Process and what it costs

First call. Free, thirty minutes. Bring the product, the service or the feeling you want the page to carry, and I'll say whether 3D helps and sketch what it would show.

Prototype in the browser. Before the full build, a rough scene on a test page, on your phone, so we judge the real thing rather than a picture of it.

Build, measure, hand over. The scene, the fallbacks and the page around it, measured against the budget above, then handed over in your own repository and hosting with the source files for the models.

I quote 3D work per project after the first call, because a product viewer and a full environment are different sizes of job. I can add it to an existing site or build it as part of website development. The marketing tiers on the pricing page don't cover it, and I'd rather give you a real number after seeing the brief than a band here.

Questions about 3D websites

Does 3D hurt SEO?

Not when it's built the way described above. Google ranks the HTML it can read and the speed it measures. If the text lives only inside a canvas or the scene blocks the page for seconds, yes, it hurts. If the scene loads after the content and the text is real, the page ranks like any other. I check both with the same tools I use for technical SEO.

Does it work on phones in Nepal?

Yes, if it's built for them. Most of your visitors are on a phone on mobile data, so the models are compressed, the scene is small, and it starts only once the page is usable. On a very old phone the visitor sees the fallback image and never knows what they missed.

Can you add 3D to my existing site?

Usually, yes. A product viewer or a hero scene can go into a WordPress, Next.js or static site without a rebuild. I look at the current page speed first, because adding motion to a page that is already slow makes the real problem worse.

What does a 3D website cost?

Quoted per project after the free first call. A single product viewer is a smaller job than a scene that runs through a whole site, so the brief decides the number. You get the price in writing with what it includes and what it leaves out.

Which tools do you use?

Three.js and WebGL for the scenes, GSAP for scroll and timeline motion, and models from your own CAD or design files or built for the project. The site stays whatever it already is; the scene is a component inside it.

When are you not the right person?

If you want a full game or a VR experience, that's a studio job. If you want motion on a site whose real problem is that nobody finds it, I'll send you to the SEO page first. And if the brief is decoration with no job to do, I'll say so.
