Future of the Web Platform: Workshop

• (15m) Emscripten hello world
  • Note: if you haven't installed emscripten, do that instead. http://kripken.github.io/emscripten-site/docs/getting_started/Tutorial.html#tutorial
  • emcc tests/hello_world.c
  • node a.out.js
  • mv a.out.js b.out.js
  • emcc -O1 tests/hello_world.c
  • Play around in both, see what interesting observations you come up with.
    • Potential starting point: try to find the string "hello, world".
• (10m) Discuss
• (20m) Attempt to compile ammo.js
  • Download source from https://github.com/kripken/ammo.js/
  • mv builds/temp.js builds/temp-backup.js so that it won't shortcut the build process.
  • Run autogen.sh from bullet/
  • Run python make.py
    • You'll need to install automake and libtool if you haven't already.
• (20m) Explore ammo.js
  • If you didn't finish, restore your backup build
  • python -m SimpleHTTPServer, visit http://localhost:8000/examples/webgl_demo/ammo.html
  • Explore and see what interesting conclusions you can draw
    • General orientation: examples/webgl_demo/shared.js contains worker code.
    • Potential starting point: Why is it so slow if the benchmarks claim such good performance?
• (10m) Discuss
