MoiréFieldAnimated Moiré Pattern Generator
MoiréField is an interactive animated moiré pattern generator for creating optical interference, layered geometric patterns and evolving moiré effects directly in the browser.

How the process works
Two independent pattern layers form the image. Changes to spacing, angle, position and distortion alter the interference between them, while Auto Movement turns those relationships into animated moiré.
Inputs and source material
Start from the built-in geometric pattern generators; no imported media is required.
Save and export
Export a still image or record a WebM animation in the browser, with landscape, square, portrait and custom canvas sizes.
- 01Choose two pattern layers and select a pattern for each.
- 02Adjust spacing, angle and position; use Lab warps or Auto Movement to animate their relationship.
- 03Choose a canvas size, including vertical 9:16, then export a still or record WebM in the browser.
Five processing engines, image/video input, masking and live output smoothing are available in the current web app.
