About this tool
Ink Spread is a free online visual effect. Canvas 2D ink wash diffusion and bleeding effect. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
The whole process is purely front-end animation, based on a simplified version of fluid simulation based on Canvas, using Berlin noise to control the diffusion direction of the ink, and a gradual transparency to simulate the diffusion effect.
After opening the page and clicking on the screen, ink will be dropped from the click position. The ink will slowly spread in the water to form a beautiful pattern. Parameters such as ink color, diffusion speed, and water viscosity can be adjusted.
Suitable for artistic creation, ink-and-ink decoration, or purely appreciating the flowing beauty of ink diffusion. The realization principle is Berlin noise and transparency gradient.
Ink diffusion is a visual effect that simulates the diffusion effect of ink in water. It is based on Canvas to render the flow and diffusion of ink in real time.
