About this tool
Spirograph is a free online visual effect. Draw mesmerizing hypotrochoid curves by tuning the gears, speed and colors. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, an animation of a spiral plotter will be displayed, with multiple gears rolling each other, and the tip of the pen draws a complex spiral pattern on the paper. Parameters such as the radius ratio of the gear and the position of the pen tip can be adjusted to generate different patterns.
The whole process is pure front-end animation, drawing spiral curves based on Canvas 'parametric equations, and using trigonometric functions to calculate the position of the pen tip. The animation process is slow and eventually forms a beautiful pattern.
It is suitable for use as a mathematical art display, geometry popularization, or purely appreciating the symmetrical beauty of spiral patterns. The realization principle is the parametric equations of the hypocycloid and the epitroid.
A spiral graph is a visual effect that simulates a spiral graph, which generates complex spiral patterns based on mathematical formulas.
