coverage

The orders a wipe can follow.

coverage: { directional, radial, angular, cells, noise }

Import effects from shaders/std and use effects.reveal.coverage.

Each word returns a Coverage for reveal.

All of them read the canvas in uv (0–1 across, y down) and correct for its aspect ratio, so a circle stays round and a diagonal stays at its true angle.

Example

coverage: coverage.radial(p('center'))

Members

• coverage.directional — A straight edge sweeping across the canvas.
• coverage.radial — A circle growing out from center, an iris wipe.
• coverage.angular — A clock hand sweeping around center.
• coverage.cells — A grid of square cells size wide.
• coverage.noise — Soft blobs eating the image away, the classic film dissolve.

• reveal — Fade the child away in coverage order as progress goes from 0 to 1.
• Coverage — The order pixels disappear in: a number per pixel from 0 (goes first) to 1 (goes last).
