Use Reaction Diffusion online for free, no download required. 51yifei offers hundreds of fun online tools.

Two virtual chemicals react and diffuse (Gray-Scott model), self-organising into coral, spots or maze patterns. Paint on the canvas to seed more.

About this tool

Reaction Diffusion is a free online visual effect. Gray-Scott reaction-diffusion grows coral and spot patterns. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.

After opening the page, it will show that two chemicals react and spread on the screen, creating patterns similar to zebra stripes, leopard prints, coral and other biological textures. Parameters such as reaction rate, diffusion coefficient, and color scheme can be adjusted.

It is suitable for being used as a science popularization of mathematical biology, a generation art display, or purely appreciating the natural beauty of reactive diffusion patterns. The realization principle is the Gray-Scott reaction-diffusion model.

The entire process is purely front-end animation, based on Canvas 'Gray-Scott model, using difference equations to simulate the reaction and diffusion of two chemical substances.

Reaction Diffusion is a visual effect that simulates the reaction and diffusion process of two chemicals, producing a pattern similar to biological textures.
