Celestial motion simulation and graphics processing device with three-dimensional perspective

Abstract

This invention provides a celestial motion simulation and graphics processing device with a three-dimensional perspective linkage, addressing the difficulty of traditional teaching methods in continuously presenting celestial spatial changes and dual-perspective transitions. The device includes an input unit, a storage unit, a processing unit, and a display unit. The processing unit generates a time variable based on the time control command received from the input unit and, combined with the celestial motion parameters stored in the storage unit, calculates in real-time the relative spatial coordinates of the first, second, and third celestial bodies to generate a macroscopic celestial scene image. Simultaneously, based on the observation position and light source direction on the second celestial body, it calculates and generates a corresponding first-person lunar phase image. Finally, the display unit synchronously displays the aforementioned dual-perspective images side-by-side, achieving an intuitive and continuous presentation of the causal relationship between celestial motion and lunar phase changes through a single time variable operation.
