- **Realistic Shadow Mapping**: See realistic 3D shadows cast by buildings and terrain at any time of day, in any season.

- **Sun Times & Position Data**: All the sun data you need for any date and location: times for sunrise, sunset, golden hour, blue hour, and every twilight phase — plus azimuth, elevation, shadow ratio, and total day length.
- **Cloud & Weather Forecast**: Hourly cloud cover layered with sun position data — spot the clearest window for shooting, planning, or just catching a perfect sunrise.
- **Home Screen Widgets**: Live sun data from your home screen — track current elevation, azimuth, and shadow ratio, or check today's sunrise, sunset, and key light times at a glance.
- **Street View Sun Path**: Panorama and street-view sun path planning for checking light direction from a ground-level scene.

## Calculation Methodology

SunCast calculates solar position using astronomical formulas derived from Jean Meeus solar position algorithms, the same class of calculations commonly used for sunrise, sunset, solar azimuth, solar elevation, and twilight estimates.

These calculations produce the sun's apparent position for a selected place and time, including solar azimuth, solar elevation, sunrise, sunset, solar noon, golden hour, blue hour, and civil, nautical, and astronomical twilight estimates.

- **Shadows**: SunCast calculates shadows from solar position and the available scene, building, terrain, or user-placed geometry.

- **Weather**: SunCast uses Apple WeatherKit for weather and cloud-cover forecast data.

- **Maps and terrain**: SunCast uses map and terrain context from various map providers, including Apple MapKit and Google Maps.

## Limitations

SunCast is designed for planning light, shadows, photography, gardening, property sunlight, and preliminary solar or construction review. It is not a substitute for safety-critical navigation, legal surveying, engineering certification, or permitting analysis.
