    • Sunpath 3D is an advanced solar analysis tool designed to visualize solar paths and shadow projections in a 3D environment. Developed by Andrew Marsh, it enables users to test how trees, neighboring buildings, and other obstructions impact sunlight exposure. By importing 3D models, users can analyze the influence of shadows on PV panel yields and building interiors, supporting efficient design and energy planning.

      The tool allows users to adjust locations on an interactive map, select specific times of day, and simulate solar paths for any date. Using the "Start Animating" function in the top bar (shortcut "P"), the solar curve of any day can be played. Sunpath 3D proves invaluable for adhering to local regulations, such as Zurich’s 2-hour shadow rule for high-rise buildings.

      Built with JavaScript, WebGL, and SVG, Sunpath 3D offers responsive, real-time rendering, making it accessible on desktops and mobile devices. It seamlessly integrates 3D visualizations and 2D charts, optimizing animations for smooth performance. Sunpath 3D is a powerful tool for architects, urban planners, and designers aiming to optimize solar access and shading strategies for building projects.
