Metaballs Free WebGPU shader

Forms that find each other.

Soft, merging metaballs with a pointer-driven blob. Tune the field, halo and colors, then export a free WebGPU background for React.

Part of the Free collection for Aperveil 1.0. Public live preview and Color Looks are open. Free Export Kits do not require an account. Purchasing is not available yet.

THE SYSTEM BEHIND THE SURFACE

Inside Metaballs.

Metaballs sums a procedural blob field and shapes its threshold into merging forms. A pointer blob joins the field; ball size, threshold, halo and rim define the result.

The current editor does not expose blob count. These are implicit shapes, not simulated liquid particles or draggable independent objects.

0.444 ms legacy timing (method not recorded; not a pure GPU measurement). 1440x900 @ dpr 1.5; Metal driver on macOS Version 26.6.2 (Build 25G83); measured 2026-09-03. This is a recorded headless sample, not a browser FPS or mobile-performance guarantee.

Blob size

Size of the blobs.

Merge threshold

Lower makes the blobs fatter and merge sooner.

Halo

A softer second threshold that keeps the edges from looking like cut vinyl.

Rim light

Bright rim where each blob's surface turns over.

Color Looks preserve these settings. Open the editor for all 13 controls.

KEEP THE SOURCE. KEEP THE CONTROL.

From preview to your project.

Choose a Look, tune it in the editor, then download the Export Kit. Install the runtime and copy the generated component into your project.

Every control in the editor is a typed prop. Leave a prop out to keep the value you exported; change one and the running shader updates without restarting. Give the surface a size and pass fallback for browsers without WebGPU.

In Next.js, use a client component and give its container an explicit size. Keep headings, links and accessible content in HTML above the decorative canvas.

Markdown guide

Usage example — download Metaballs.tsx from the editor first. This example imports that local file; it is not the shader component itself.

Terminal

npm install ./vendor/aperveil-runtime-0.1.0.tgz ./vendor/aperveil-react-0.1.0.tgz

Metaballs usage

"use client";

import Metaballs from "./Metaballs";

export default function Hero() {
  return (
    <Metaballs
      className="hero-shader"
      ballSize={0.135} background="#0a0d17ff"
      fallback={<div className="hero-shader-fallback" />}
    />
  );
}

// .hero-shader { width: 100%; height: 560px; }

Download and extract the complete Export Kit first. Run its local package command from the ZIP root, then copy the component into your project. Public npm and CLI distribution is coming soon.

THE SURFACE IN CONTEXT

Made for a real interface.

Bring a playful but controlled organic accent to a creative-tool launch. Use generous margins around a compact headline so the merging forms remain readable.
