【Sunlight Calculator - Home Sun Exposure Analysis Tool】
Sunlight Calculator is a professional home sun exposure analysis tool that helps you objectively evaluate lighting conditions when choosing a property. Through 3D modeling and solar trajectory simulation, it provides visualized sunlight data for your reference.

Core Features
【Multiple Modeling Methods】

Floor Plan Modeling: Import residential community floor plans to quickly build a 3D model
Map Modeling: Select the community location on a map to automatically obtain geographic coordinates
Building Spacing Modeling: Enter building spacing and height parameters to simulate shading conditions
Unit Layout Simulation: Simulate sunlight distribution and shadow changes at different times of day on the floor plan
Model Editing: Adjust floor height, building orientation, and other parameters
Save & Share: Models can be saved locally or shared with family and friends

【Professional Sun Exposure Analysis】

Solar Trajectory Simulation: Display the sun's path at any date and time throughout the year
Sunlight Duration Statistics: Calculate cumulative daily sunlight hours at each location
Time-Period Analysis: View lighting conditions in the morning, afternoon, and throughout the full day
Winter/Summer Comparison: Compare lighting differences on key dates such as the winter and summer solstices
Sampling Point Analysis: Select specific locations to view detailed sunlight data
Dynamic Playback: Play full-day sunlight change animations to intuitively understand lighting patterns

【3D Heatmap Display】

Color Grading: Red–orange–yellow–green–blue gradient representing lighting from excellent to poor
Layer-by-Layer Display: View sunlight distribution for each floor individually
Multi-Building Comparison: Display heatmaps for multiple buildings simultaneously for easy side-by-side comparison
Precision Settings: Adjust calculation precision to balance speed and accuracy
Data Labeling: Display sunlight duration values directly on the 3D model

【Window View Simulation】

Perspective Switching: Simulate the field of view looking outward from different floors
Obstruction Analysis: Show the degree to which buildings ahead obstruct the view
Landscape Assessment: Determine whether greenery, water features, and other scenic resources are visible
Floor Comparison: Compare view differences across different floors
Distance Measurement: Calculate the actual distance from a window to the building ahead
Height Annotation: Display the relationship between line-of-sight height and the height of obstructing structures

【Report Generation & Export】

Single-Floor Report: Generate a detailed sun exposure analysis report for an individual floor
Batch Reports: Generate comparison reports for multiple buildings or floors with a single tap
Multiple Formats: Supports export as PDF, PNG image, or CSV data spreadsheet
Custom Templates: Choose from different report styles and content modules
Print Optimization: PDFs are automatically paginated to fit standard A4 paper
