Built with Three.js and OpenStreetMap data. Supports any city.\n\n\u003cp align=\"center\"\u003e\n  \u003cimg src=\"https://github.com/mkturkcan/Shadowcast/blob/main/assets/example.png?raw=true\" width=\"512\" /\u003e\n\u003c/p\u003e\n\n## Features\n- Real-time shadow casting with adjustable light position\n- Orthographic and perspective camera modes\n- Material Design UI with dark theme\n- Physically-based rendering with metallic materials\n- Building heights from actual OpenStreetMap data\n- Soft shadows with adjustable parameters\n- Responsive design that scales to any viewport\n\n## Setup\n1. Clone the repository\n2. Serve with any HTTP server (e.g., `python -m http.server` or `npx serve`)\n3. Open in a browser that supports ES modules\n4. Use polygonhelper.html to edit the area to be used for the renders\n\n## Dependencies\n- Three.js 0.153.0\n- Materialize CSS 1.0.0\n- No build process required\n\n## Data\nBuilding footprints and heights are fetched dynamically from OpenStreetMap via Overpass API, centered on Manhattan.\n\n## License\nMIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkturkcan%2Fshadowcast","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmkturkcan%2Fshadowcast","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkturkcan%2Fshadowcast/lists"}
