SDL2 and Emscripten WebGL Demo

This repository is a simple demonstration of compiling SDL2 C++ code into WebAssembly using the Emscripten compiler, which can then be executed in a web browser using WebGL. The demo showcases a bouncing square which starts from the centre of the window and move in a random direction. When it collides with the window border, it will bounce back, changing its colour randomly.

Technology Stack

The application is built using the following technologies:

1. SDL2: Simple DirectMedia Layer is a cross-platform development library designed to provide low-level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D.
2. C++: The application logic is written in C++.
3. Emscripten: Emscripten is an LLVM-to-Web Compiler. It takes LLVM bytecode (e.g., compiled from C/C++ using Clang, or from another language) and compiles that into WebAssembly, which can be run on the web.
4. WebAssembly (Wasm): Wasm is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for the compilation of high-level languages like C++, enabling deployment on the web for client and server applications.
5. WebGL: WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins.
