About this tool
Constellation is a free online visual effect. Star particles with mouse-drawn constellation lines. 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 starry background will be displayed, with hundreds of stars randomly distributed, and some stars will be automatically connected to form a constellation pattern. Parameters such as star density, connection distance, and constellation style can be adjusted.
The whole process is purely front-end animation, drawing stars and connections based on Canvas, and using distance to determine which stars should be connected between them. Stars will flash randomly, and connections will have a faint glowing effect.
Suitable for astronomy science, constellation theme decoration, or purely appreciating the romantic effect of the starry sky. The implementation principle is distance threshold determination and transparency animation.
Constellation Connection is a visual effect that simulates the connection of stars and constellations. It renders stars and connections in real time based on Canvas.
