Classic corporate site
Designed for the company but static: pages flow downward, content is read. Its job is to inform; experience and brand storytelling come second.

What is a 3D scroll motion website? A guide to sites that live as you scroll
A 3D scroll motion website is a type of website where three-dimensional scenes, camera moves and animations progress fluidly as the user scrolls the page. The page is not read like a document, it is driven like a scene: every scroll advances the story one step. It is built with Three.js, WebGL and WebGPU. This guide covers the definition, the differences, the sourced numbers and the use cases.
What is a 3D scroll motion website?
A 3D scroll motion website turns the scroll gesture into a controller: as the user scrolls down, the camera moves through a scene, a product rotates and splits into its layers, a building rises floor by floor, and text enters the stage at exactly the right moment. On a classic site, content is stacked and read; on a 3D scroll motion site, content is divided into scenes and experienced. The technical foundation is real-time 3D rendering in the browser with Three.js, WebGL and the next-generation WebGPU, plus scroll-driven techniques that bind scrolling to animation. UNALSOFT builds these sites WebGPU-first as part of its 3D Scroll Motion Websites service; the unalsoft.com homepage is itself a live example of this approach.
Classic corporate site, ready-made theme and 3D scroll motion
Three approaches are often confused. The distinction is simple: a classic corporate site lists information, a ready-made theme fills in a template, 3D scroll motion stages the brand.
Ready-made theme / template site
A template used on thousands of sites, filled with your content. Fast and cheap; in exchange, brand differentiation drops and plugin weight can slow the site down.
3D scroll motion
Scenes designed for the brand are bound to scrolling: the user drives the story. It is an original production, built on a performance budget.
| Feature | Classic corporate site | Ready-made theme / template | 3D scroll motion |
|---|---|---|---|
| Design source | Custom for the company | Ready template, same across many sites | Scene design custom to the brand |
| Scroll experience | Page flows downward | Page flows downward | Scrolling drives the story |
| 3D scenes and camera moves | None | None, limited to stock effects | Yes, real-time rendering |
| Brand differentiation | Medium | Low, the template is recognizable | High, scenes are unique to the site |
| Performance engineering | Varies by project | Can slow down under plugin weight | Built on a performance budget |
How do speed and experience affect conversion?
A 3D experience only creates value together with speed; that is why the performance budget is the core of the craft. Every figure below is sourced:
3x
A site that loads in 1 second was measured to have a conversion rate 3 times higher than a site that loads in 5 seconds. Source: Portent.
8.4%
A 0.1 second improvement in mobile site speed increased retail conversions by 8.4% (37 brands, 30 million sessions). Source: Deloitte, Milliseconds Make Millions.
32%
When mobile page load time goes from 1 second to 3 seconds, the probability of the user bouncing increases by 32%. Source: Google.
90%
In the same research, when load time goes from 1 second to 5 seconds, the increase in bounce probability reaches 90%. This is why a 3D site has to be built fast. Source: Google.
How does a 3D scroll motion site work?
Behind the curtain, several systems run at once; the user only sees a fluid story:
The scroll controller
The scroll amount is converted into a progress value; camera, light and animations are bound to it. When the user stops, the scene stops.
Real-time rendering
The scene is drawn every frame on the browser's graphics processor: WebGPU-first, WebGL on devices without support. No plugin, no install.
Scene-by-scene storytelling
The story is split into beats: each scene carries one message, text enters and exits at the right moment. The script is written before the design.
Performance budget
Assets are lazy-loaded, scripts run async/defer, frame time is budgeted. The goal is clear: the 3D scene must run without breaking Core Web Vitals.
Graceful degradation
On weaker devices and with the reduced-motion preference, the scene simplifies or switches to a static alternative; content stays accessible in every case.
SEO foundation
Content lives as real HTML that search engines can read; the 3D scene is built on top of it. Visual craft and findability are not alternatives to each other.
Where is 3D scroll motion used?
The rule is simple: any brand with a visual story to tell is a candidate. Frequently built examples:
Launch sites
A single-page digital show for a new product or brand, staged toward a finale.
Real estate projects
From plot to key: the project rises floor by floor as you scroll, units and views are toured scene by scene.
Product configurators
Color, material and parts are chosen in a 3D scene; the customer builds the product themselves, then decides.
3D product stories
The product rotates, opens, splits into its layers; each feature is told in its own scene.
Brand showcase sites
Experience sites for agencies, studios and premium brands that turn the craft itself into proof.
Trade fair and kiosk experiences
Interactive 3D presentations running on a touchscreen at your stand; the site keeps living after the fair.
How does UNALSOFT do this work?
Many build 3D sites; what makes the difference is measuring the performance and the craft openly.
The live demo is public
The unalsoft.com homepage itself is the live demo of this craft: real, browsable proof instead of a showcase reel.
Performance is published
The homepage measures LCP ~0.7 s and CLS ~0.0006; accessibility, best practices and SEO scores of 100. Despite a real-time 3D scene.
A WebGPU-first engine
The scene is built WebGPU-first and degrades gracefully on unsupported devices; smoothness is targeted on every device, mobile included.
Frequently asked questions
What is a 3D scroll motion website?
It is a type of website where three-dimensional scenes, camera moves and animations progress fluidly as the user scrolls the page. The page is not read like a document, it is driven like a scene; it is built with Three.js, WebGL and WebGPU.
What is the difference between a 3D scroll motion site and a ready-made theme site?
A ready-made theme is a template used on thousands of sites, filled with your content; a 3D scroll motion site is an original production where scenes designed for the brand are bound to scrolling through real-time rendering. The first is read, the second is experienced.
Does 3D scroll motion hurt SEO and speed?
Not when it is set up correctly. A performance budget, lazy loading, async/defer scripts and graceful degradation by device capability are the standard of this craft. Live example: the unalsoft.com homepage runs on 3D scroll motion and has measured LCP ~0.7 s and CLS ~0.0006.
Which technologies is a 3D scroll motion site built with?
The core technologies are Three.js, WebGL and the next-generation WebGPU; scroll-driven animation techniques handle the scroll sync. UNALSOFT builds these sites WebGPU-first, falling back to WebGL on devices without WebGPU support.
Which businesses is a 3D scroll motion site right for?
Brands that want to tell their product or project visually: launches, real estate projects, product configurators, brand showcase sites and trade fair experiences. If the goal is not to list information but to tell the brand as a memorable story, this format is a candidate.
What does a 3D scroll motion website cost?
The number of scenes, 3D asset production and interaction depth vary from project to project, so a single figure would be misleading; scope and budget are clarified in a discovery call. In that call, a scene-by-scene roadmap is drawn up together.
