@gpujs/expo-gl - A GPU.js extender for use with React Native's Expo library

This package allows you to use GPU.js with Expo to get a native GPGPU.

Installation

1. Setup Expo - https://docs.expo.io/versions/latest/introduction/installation/
2. Add the following to use @gpujs/expo-gl:

  import { GLView } from 'expo-gl';
  import { GPU } from '@gpujs/expo-gl';
  GLView.createContextAsync()
    .then(context => {
      const gpu = new GPU({ context });
      const kernel = gpu.createKernel(kernelFunctionHere, kernelOptionsHere);
      kernel();
    });

3. Visit https://github.com/gpujs/gpu.js for documentation on kernelFunctionHere, kernelOptionsHere, as well as the api.
4. Run your expo from Android or iOS and have native GPGPU support!
5. Have fun!

Example

import { GLView } from 'expo-gl';
import { GPU } from '@gpujs/expo-gl';
GLView.createContextAsync()
  .then(context => {
    const gpu = new GPU({ context });
    const kernel = gpu.createKernel(function() {
      return 1;
    }, { output: [1], debug: true });
    console.log(kernel());
    gpu.destroy();
  });
