Terra Nav — 3D Travel Landing Page

A complete, scrollable travel landing page with the 3D built into it: a glass mega-menu that reshapes a live 3D landscape. 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, one displaced terrain shader with four biomes, glass mega-menu navbar, scroll-driven flight. What a visitor can do: hover a region in the Discover menu to reshape the land, scroll to fly on, 4 presets (Glaciers, Volcanoes, Dunes, Islands). Best for: Travel and tour operators, hotels and resorts, outdoor brands, airlines. 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.
