London Explorer Digital Flipbook

Interactive 3D Digital Flipbook

London Explorer turns boring PDF travel guides into a beautiful 3D digital book you can actually flip through. Pages curl and turn with realistic physics, just like a real book. Browse stories, maps, and audio guides — even without internet.

CHALLENGE & SOLUTION

FromComplexProblemsTo SimpleSolutions

Fixing slow page speeds, cart drop-offs, and confusing systems with modern, reliable engineering.

THE CHALLENGE

What Needed Fixing

PDF guides were hard to use on phones — too much pinching and zooming. Standard flipbook tools looked stiff and ran slow.

HOW WE FIXED IT

How We Solved It

We built a custom 3D page-turn effect with smooth drag-and-flip physics that feels like turning real paper, with realistic shadows and curling.

01
Shader Pipeline

WebGL 2.0 GLSL Shaders

Vertex deformation creating parabolic paper curls with dynamic light reflection.

02
Gesture Engine

GSAP Observer & Pointer Events

Universal touch/mouse velocity inertia tracking.

03
Rendering Core

OffscreenCanvas Worker

Pre-rasterizes high-density retina spreads off the main UI thread.

04
Offline Storage

IndexedDB + Workbox PWA

Instant offline page access without network reliance.
