[THR2PXL]

Introduction

An efficient model-to-pixel transformation with motion effects, leveraging WebGL's hardware acceleration and GPGPU through Three.js:

Demo

[!TIP] If you would like to implement a similar effect on a 2D image, you can use the related library d3p1/img2pxl.

[!NOTE] This library was inspired by these excellent tutorial:

Three.js Journey - GPGPU Flow Field Particles.

Installation

You can install this library using a package manager like npm:

npm install @d3p1/thr2pxl

Or you can use a CDN like jsDelivr and this importmap in the <head> of your html file:

<head>
  ...
  <script type="importmap">
    {
      "imports": {
        "@d3p1/thr2pxl": "https://cdn.jsdelivr.net/npm/@d3p1/thr2pxl@<version>/dist/thr2pxl.min.js",
        "three": "https://cdn.jsdelivr.net/npm/three@<version>/build/three.module.min.js",
        "tweakpane": "https://cdn.jsdelivr.net/npm/tweakpane@<version>/dist/tweakpane.min.js"
      }
    }
  </script>
  ...
</head>

[!NOTE] Remember to replace the <version> with the actual version of thr2pxl and its peer dependencies (three and tweakpane). To do that, you can check the package.json of the last release and get required versions from there.

Usage

Using this library is straightforward:

Go to our builder page and make the desired customizations in the tweak panel to achieve the desired effect.
Use the Copy button to obtain the configuration that produces the desired effect.
Instantiate the library with the configuration copied in the previous step, for example:

import Thr2pxl from '@d3p1/thr2pxl'

new Thr2pxl({
  models: {
    0: {
      src: {
        highPoly: <model-high-poly-src>,
        lowPoly: <model-low-poly-src>
      },
      width: <model-width>,
      height: <model-height>,
      point: {
        size: 5,
        motion: {
          frequency: 0.1,
          strength: 1.5,
          ratio: 0.25,
          lifeDecay: 0.2
        }
      }
    },
    pointer: {
      strength: 0.2,
      minRad: 1,
      maxRad: 2,
      pulseStrength: 0.2,
      pulseFrequency: 1
    }
  }
})
