01 — The Problem

The web stopped
telling stories.

Traditional websites scroll through static content without emotion or engagement. Product pages list features but fail to make users feel the product.

Apple changed the game with cinematic scroll experiences. That pattern — immersive storytelling through motion — is what this project explores and implements from scratch.

02 — The Solution

An experience engineered from first principles.

01

Scroll-Based Animations

GSAP ScrollTrigger maps every pixel of scroll progress to precise animation states — no jank, no guessing.

02

3D Product Rendering

Three.js renders a 3D product model directly in the browser, responding to scroll position and user interaction.

03

Timeline Control

GSAP timelines orchestrate complex multi-element sequences with precise control over easing, delay, and duration.

04

Pinned Sections

Key storytelling moments pin the viewport while content animates through — mimicking Apple's signature scroll behavior.

04 — Engineering Decisions

Chosen carefully.
For a reason.

01

GSAP ScrollTrigger

The gold standard for scroll-linked animations. Declarative, composable, and battle-tested for 60fps delivery on all devices.

02

Three.js for 3D

Native WebGL abstraction that gives full control over the scene graph, lighting, materials, and camera — without a heavy game engine overhead.

03

Zustand state

Animation systems need global state without re-render overhead. Zustand provides reactive stores with zero boilerplate and excellent performance.

04

GSAP Timelines

Sequential control over complex multi-step animation choreography with pausing, reversing, and label-based seeking.

05

Pinned sections

Viewport pinning keeps users in a controlled storytelling zone — the motion happens, they stay still. It's how immersion is engineered.

05 — Performance

60fps.
No exceptions.

60fps target

Animation loop driven by GSAP's ticker, synchronized with requestAnimationFrame — never dropping frames on GPU-composited layers.

Minimal re-renders

Zustand subscriptions are scoped to animated values only. React never re-renders during animation ticks.

Efficient asset loading

3D models and textures are loaded asynchronously with progress feedback before the experience begins.

Timeline pooling

GSAP timelines are created once and scrubbed via ScrollTrigger — no new animation objects per scroll event.

06 — Product Thinking
"A website should make you feel something — not just inform you."

The core question throughout was: what does it feel like to experience this product? Not what features does it have. That shift in thinking is what separates an Apple product page from a spec sheet.

Storytelling through motion isn't decoration. It's the product.

07 — Impact

What this proves.

AdvancedFrontend Engineering

GSAP ScrollTrigger and Three.js are the tools of world-class frontend engineers — not beginners.

DistinctPortfolio Differentiation

Immersive interactive experiences are rare. Most portfolios show dashboards and CRUD. This shows something different.

PremiumUser Experience

Users spend 3x longer on scroll-animated pages. Engagement is the only metric that matters.

Scroll. Watch it move. That's the engineering.

Every pixel of scroll triggers a calculated animation state. The result feels effortless because the work underneath it wasn't.
