3D Extruded Buildings & Urban Footprints
Real-world 3D building extrusions with dynamic sunlight shadows, terrain DEM elevations, and pitch/bearing camera controls.
Marketing navbar that starts transparent over the hero and fades in a bordered, blurred surface once the page scrolls, with a nav row, theme-neutral CTA pair, and a mobile sheet.
