How to build osgemscripten example
==================================
### 1. Install Emscripten
Download and install [Emscripten portable SDK](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html)
### 2. Create build directory
Run the following commands:
`mkdir /path/to/build/dir`
`cd /path/to/build/dir`
### 3. Configure example
Run the following command:
`cmake -DCMAKE_TOOLCHAIN_FILE=/path/to/emsdk-portable/emscripten/<version>/cmake/Modules/Platform/Emscripten.cmake /path/to/OpenSceneGraph/examples/osgemscripten`
This also configures OpenSceneGraph as a dependency
### 3. Build example
Run the following command:
`make`
This also builds OpenSceneGraph under `/path/to/OpenSceneGraph/build/Emscripten`
if it has not yet been built.
### 4. Launch example
Firefox only: locate and open `osgemscripten.html` file.
All browsers:
* go to the directory with `osgemscripten.html`
* run `python -m SimpleHTTPServer 8080` from there
* open `http://localhost:8080/osgemscripten.html` in any browser
You should now see red cube in your web browser.
