webgl2-wasm-sdl-sokol-sprite

Minimal sprite rendering example written in C with SDL2 for windowing, sokol_gfx for graphics API using WebGL2/GLES3, stb_image for loading image, compiled in WebAssembly with Emscripten.

Step by step

1. Clone the repositories sokol and stb in the deps folder

git clone https://github.com/floooh/sokol deps/sokol
git clone https://github.com/nothings/stb deps/stb

# else init/update submodules
git submodule update --init

2. Add an image (sky.png) in assets directory
3. Compile and build with the following command (need Emscripten installed):

emcc sprite.c -o sprite.html -Ideps/sokol -Ideps/stb --preload-file assets -s EXIT_RUNTIME=1 -s ALLOW_MEMORY_GROWTH=1 -s USE_WEBGL2=1 -s USE_SDL=2

4. Launch a web server from the output folder
5. Open sprite.hml page from web server
