Show HN: Browser-based light pollution simulator using real photometric data
🌟 Shining Light on Pollution: Browser-Based Simulator Leverages Real Photometric Data
This innovative browser-based light pollution simulator utilizes real photometric data to render urban scenes, allowing users to analyze and visualize the impact of streetlights on the environment. By driving streetlight behavior with actual photometric data, the simulator provides a practical tool for evaluating and mitigating light pollution, enabling more informed decision-making for urban planning and lighting design.
