A Particle System experiment designed to benchmark web technologies from a non trivial piece of code: ES6, Emscripten and Web Assembly

• Building the ASM.js and WebAssembly versions:

If you want to build the Web Assembly version, you need to build the Emscripten toolchain from source using the incoming branch. The master branch does NOT support BINARYEN=1 option at the moment

 [Install Emscripten Portable SDK](https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#all-os-installation-instructions-portable-sdk)
 
 [Building Emscripten from Source](https://kripken.github.io/emscripten-site/docs/building_from_source/index.html?highlight=build%20from%20source)
 
  . cd particle-system/Emscriptem
  . make
  . emcc -s NO_EXIT_RUNTIME=1 -s release/ParticleSystem.bc --post-js ParticleSystem/glue.js -o dist/asmjs/ParticleSystem.asm.js
  (or run emcc-asmjs.sh script for mac/linux users. Assumes emcc is in your PATH)
  . eemcc -s NO_EXIT_RUNTIME=1 -s BINARYEN=1 release/ParticleSystem.bc --post-js ParticleSystem/glue.js -o dist/wasm/ParticleSystem.js
  (or run emcc-wasm.sh script for mac/linux users. Assumes emcc is in your PATH)

• Building the the ES6 Particle System Library and the Test pages:

    . npm install
    . npm run build-lib-dev / npm run build-lib-prod
    (prod version is minified and without source map)
    . npm run build-tests
  

• Running the tests:

  Serve Test/. with the HTTP server of your choice ...

If you want to test Web Assembly versions, you need a browser that supports Web Assembly.

At the moment Chrome Canary, Firefox Nighly and soon in Microsoft Edge.

Performance Tests:

• ES6 vs ASM

• ES6 vs WASM

Autodesk Forge Viewer Test:

• ES6

• asm.js

• wasm

Three.js Tests:

• ES6

• asm.js

• wasm

I've been testing against the following browsers: Chrome, Chrome Canary, Firefox, Firefox Nightly and Safari. Only Canary and Firefox Nightly supports WASM, so the following benchmark only indicate those. Running WASM in a browser that doesn't support it is using a fallback which ends up being very very slow ...
