About this tool
Spiral Galaxy is a free online visual effect. Canvas 2D spiral galaxy particle rotation animation. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
When opening the page, it will display a spiral galaxy with thousands of stars distributed in a logarithmic spiral. The center of the galaxy is bright, and there are a large number of stars and nebulae on the spiral arms. The galaxy will spin slowly, creating a dynamic effect.
The entire process is purely front-end animation, drawing stars based on Canvas, using logarithmic spiral equations to calculate each star's position, and random offsets to simulate real irregularities.
It is suitable for use as astronomy science, cosmic theme decoration, or purely appreciating the magnificent beauty of galaxies. The implementation principle is the logarithmic spiral equation plus polar transformation.
Spiral Galaxy is a visual effect that simulates the structure of spiral galaxies. It renders the spiral distribution of stars in real time based on Canvas.
