While teaching a web development class, I wanted to present some benchmarks that show the performance benefits of asm.js as well as WebAssembly. I was unfortunately not able to find a suitable reference. Therefore, I implemented a simplistic raytracer in JavaScript as well as in C++ with a similar code structure while utilizing Emscripten to compile the C++ raytracer to asm.js as well as WebAssembly. For fun, I also translated the code to GLSL and am utilizing WebGL to leverage GPU computing.
