A benchmark between WebAssembly, JavaScript and native C software rendering in SDL. The WASM build is available here! When opened, it loads a base scene from a prepackaged .obj file, but any Wavefront .obj file can be opened and viewed by dragging and dropping the .obj file into the browser window on the canvas.
- WASD: movement
- Space: go up
- Left shift: go down
- Escape: release mouse lock
The same codebase is used across all build targets, with small differences between them. For the native build, CMake is used and for WASM there is a separate build_wasm.sh build script.
Emscripten is used to compile and build the WASM target so the latest version of emsdk should be installed and included in PATH. Can be built by running the script:
sh build_wasm.sh
After building the directory dest will contain the compiled target.
CMake (sudo apt install cmake on Ubuntu...) and SDL2 (sudo apt install libsdl2-dev) has to be installed before building, then build with:
mkdir build
cd build
cmake ..
make
The executable should be ready in the build directory along with the base_scene.obj file.
On Windows, the CMake GUI should be downloaded and installed along with the latest version of SDL2, then after configuring the install folder of SDL2 in CMake, the Makefile can be generated.
