WebAssembly WebVR Hello World

This is sort of a Hello World program demonstrating driving WebVR from a WebAssembly program in a browser. You should see a spinning triangle, the click/tap on the canvas, and VR mode should start.

Run a compiled version of this test at: http://2ld.de/webvrasm/

It has been tested on Firefox 56, Chrome with WebVR Emulation Extension, and the Oculus Browser on GearVR.

The code uses the WebVR 1.1 API with the C wrapper in emscripten 1.37.22. These APIs are still in flux, so future compatibility is uncertain.

Compilation and Serving

• Follow the steps here to get ready to compile WebAssembly
• Clone this directory wherever you want (git clone https://github.com/llatta/WebAssembly-WebVR-HelloWorld.git)
• cd to the root of the newly cloned directory
• Use the makefile to either build, clean up, or make a distribution version (build directory only) of the repo
  • Build: make
  • Clean: make clean
  • Build, but remove objects leaving the build dir: make dist
• You can then use python -m SimpleHTTPServer 8080 and open your browser to localhost:8080.
