WebAssembly cube - The WebGL example

For a longer time, I was unable fo found openGL example with WebAssembly technology. So I just write it. Please consider is as a small "Hello world" example with graphics.

Project contains two subprojects, one is web page, second is standalone openGL native application.

Look at demo on ZdenekSkulinek.cz

Prereqisities

• OpenGl properly installed, if uoy want use standalone application
• Emscripten installed. Recently, I am using version 2.0.29.
• CMake. I have targetted project for version 3.0.
• CLion IDE is optional. Its only one proprietal software that I am using. It's not neccesary, you run project from commaned line, of cource.
• Python 3. version is not important, take latest.

Run in web browser

I have use Python http server. Cmake copies all files into root of project, so you can run:

python3 -m http.server 8000

in root and and navigate to, surprisingly, http://localhost:8000.

Building webassembly project

You need to find toolchain file inside your emsdk directory. For example, if I have emsdk indtalled on /home/zdenek/dev/emsdk.

mkdir build-wasm
cd build-wasm
cmake -D CMAKE_BUILD_TYPE=debug -D CMAKE_TOOLCHAIN_FILE=/home/zdenek/dev/emsdk/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake ../project-wasm/
make

and run...

cd ..
python3 -m http.server 8000

Building standalone project

cd project-stand
cmake ../project-stand/
make

and run...

./cube-stand
