About this tool
Eclipse Simulator is a free online visual effect. Solar and lunar eclipse 3D simulation with shadow cones, inclination and coverage detection. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
It is suitable for use as astronomy science, solar eclipse theme display, or purely appreciating the spectacular effects of solar eclipses. The implementation principle is circular occlusion calculation.
The whole process is purely front-end animation, drawing celestial bodies based on Canvas and using circular occlusion to simulate the process of eclipse.
After opening the page, the process of an eclipse or lunar eclipse will be displayed. The moon slowly blocks the sun or the earth blocks the moon, resulting in an eclipse or lunar eclipse effect. The size of the celestial body, orbital parameters, observation angles, etc. can be adjusted.
Eclipse Simulator is a visual effect that simulates the process of eclipses and lunar eclipses. It renders celestial occlusion in real time based on Canvas.
