Sun Court · Neighborhood Light
Turn a 3D neighborhood in your hands and follow the light. Change city, season, civil time and north direction; calculate 6-minute window sunlight samples, reveal a facade heatmap and inspect individual apartments. Bundled sample neighborhood, orbit/zoom/pan, English/Chinese, guide and reset. A browser-native interactive light study, not a regulatory assessment.
