Software rendering in 500 lines of bare C++

An author presents a tutorial series on software rendering that teaches how 3D graphics APIs like OpenGL and Vulkan work by building a simplified renderer from scratch in approximately 500 lines of bare C++. Students learn fundamental graphics concepts by manually implementing pixel-setting, line drawing, and triangle rendering without external graphics libraries, starting from a basic TGA image class and progressively building up to rendering 3D models with textures.
