Full-page experience · Open playground

Explore seeded marble, paper, and cellular surfaces as backgrounds and repeating fills.

Try it

Switch materials, cycle the palette, and make a new variation.

What to learn

Reuse procedural texture output in Canvas composition.
Keep texture generation independent of display size.

Integration boundaries

Uses the optional @pibbl/core/textures package and the public render-layer lifecycle.
Texture renderer sources are borrowed for the synchronous callback; Pibbl owns presentation.

This is a Pibbl Canvas example. Its mount owns its runtime resources; call its controller’s dispose method when removing it. The preview starts automatically unless reduced motion is enabled; Stop disposes the mount. Preserve the source’s logical canvas size and aspect ratio. Native HTML is not captured by Canvas filters.

Complete source

Host setup for this source: use a canvas with width 880 and height 630, compile with jsx: "react-jsx" and jsxImportSource: "@pibbl/core", import its default mount, and call const controller = mount(canvas) after attaching the canvas. Call controller.dispose() before removing it.
