## 概述

Interactive visualization of relativistic stellar aberration and the headlight effect. Features the relativistic aberration formula: tan(θ') = sin(θ)/(γ(cos(θ) - v/c)), classical aberration: sin(θ - θ') = v/c, and headlight effect demonstrating forward concentration of light. Real-time 3D starfield visualization showing apparent shift in stellar positions due to observer motion, with adjustable velocity (v/c from 0 to 0.99) and field of view (60° to 180°). Side-by-side comparison views: rest frame vs moving frame observation. Star density control (100-2000 stars) with randomized brightness and spectral colors. Rotation animation with speed control (0-3x) to demonstrate aberration from all directions. Preset velocity buttons for quick comparison: stationary, 0.5c, 0.9c, 0.99c. Real-time statistics display: Lorentz factor γ, aberration angle for perpendicular stars. Visual demonstrations include: fisheye stereographic projection showing spherical sky, dramatic forward concentration at high velocities (at 0.99c, 180° field compressed to ~8°), relativistic 'searchlight effect' where universe appears concentrated ahead for near-light travelers, and comparison with classical rain analogy. Educational content covers aberration formula derivation using Lorentz transformations, Bradley's 1725 discovery proving Earth's motion, difference between classical and relativistic aberration, practical applications in astrometry (stellar position corrections), GPS satellite navigation, cosmic ray observations, and relativistic space travel visualization. Multi-language support (zh, en, fr, de, es, pt, ru).
