Day 91. Snow Dome Anywhere (3D + Particles) ❄️

This browser experiment keeps a dense 3D city readable, then layers winter atmosphere through particles and glow.

Inspiration: FOSS4G Bucharest 2019 - Iván Sánchez Ortega and Niene Boeijen.
BTW: FOSS4G Europe 2026 (Timișoara, 29 June - 3 July) - https://2026.europe.foss4g.org
Do not miss it - it might change your life.

Day 90. Making Lights 🌚🌞

MapLibre GL JS over lower Manhattan keeps the same OSM extrusions, but routes them through custom WebGL where SunCalc positions the light and day or dark MapTiler JSON swaps at dawn and dusk so the basemap tracks the shader, while GSAP, lil-gui, and Turf handle animated time, uniforms, and footprint popups.
