## 概述

Interactive visualization of the complete lunar phase cycle (29.53-day synodic month) demonstrating sun-earth-moon positions and shadow formation. Features three viewing modes: Orbit View (top-down perspective showing Moon's orbital position relative to Earth and Sun), From Earth View (realistic moon phase appearance as seen from our planet), and Split View (simultaneous comparison). Interactive day progress control (0-29.53 days) with automatic animation speed adjustment (0.1-5.0x). Real-time calculation and display of phase angle (0-360°), illumination percentage using formula (1 - cos(θ)) / 2 × 100%, current phase name (New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent), and moon age. Adjustable display parameters: moon size (20-60 px), orbit radius (100-200 px). Comprehensive visual elements: Sun rays showing light direction, Earth (observer position), Moon's orbital path, phase angle indicator, major phase icons (New Moon, First Quarter, Full Moon, Last Quarter). Toggle options for orbit path, sunlight rays, phase names, phase angles, and time scale. Educational content covers lunar cycle fundamentals (synodic month 29.53 days vs sidereal month 27.32 days), phase geometry (elongation angle determination), observation tips (waxing vs waning, hemisphere differences, rise/set times), eclipse connections, and cultural significance (calendars, agriculture, religious festivals, tides). Real-world applications: timekeeping systems, agricultural planning, navigation, biological cycles, tidal predictions, astronomical education. Multi-language support (zh, en, fr, de, es, pt, ru).
