About this tool
Aurora Borealis is a free online visual effect. Canvas 2D gradient aurora animation, dynamic flow. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, a night sky scene will be displayed. Beautiful auroras appear in the sky. The auroras flow in the sky like curtains, and the color will gradually change from green to purple. Parameters such as aurora intensity, color scheme, and fluttering speed can be adjusted.
The whole process is purely front-end animation, with Canvas based Berlin noise controlling the shape and position of the aurora, and using gradient filling to achieve color transition.
It is suitable for use as a night sky themed decoration, a romantic atmosphere background, or purely appreciating the gorgeous beauty of the aurora. The implementation principle is Berlin noise plus gradual filling.
Aurora is a visual effect that simulates the effect of northern lights. It is based on Canvas to render the flow and color changes of the aurora in real time.
