Software Rendering in 500 Lines of Bare C++

I guide students through building a software renderer from scratch using only 500 lines of bare C++. By avoiding third-party libraries and graphics APIs like OpenGL or Vulkan, we manually implement core concepts to understand how modern 3D graphics actually work. This hands-on approach transforms complex theory into a tangible project, proving that deep understanding comes from writing the code yourself rather than relying on pre-built tools.
