Ice Cave — 3D Consulting Landing Page

A complete, scrollable consulting landing page with the 3D built into it: fly through a faceted blue ice tunnel toward the light as you scroll. It is one self-contained HTML file, built entirely in code, with no image files, no 3D models and no build step. Under the hood: Three.js, noise-carved tunnel seen from inside, faceted with screen-space normals, exit-light shading and fog, instanced icicles, snow particles, scroll fly-through along a curved path. What a visitor can do: scroll to fly through the cave, move to look around, 4 presets (Glacier, Emerald, Amethyst, Ember). Best for: Strategy and data consultancies, climate and polar research, outdoor and expedition brands, cinematic product stories. Three.js loads from a CDN through an import map and the type (Instrument Serif, Inter) from Google Fonts, so there is still nothing to install. The page is real HTML — a navigation bar, a full-height hero, content sections, a call to action and a footer — so the brand name, headlines and cards are edited as plain text. Colours, counts and speeds sit in a CONFIG block and a PRESETS array, colour themes restyle the page and the 3D together from a small swatch pill, ?embed hides the pill and ?tour scrolls the page by itself.
