- The article demonstrates how 3D graphics APIs like OpenGL and Vulkan work by writing a simplified software renderer from scratch in C++, using about 500 lines of code.
- No third-party libraries are used except for a TGA image class; the renderer generates an image of a 3D model without any graphical interface.
- Students typically require 10–20 hours of programming to produce such a renderer, and the initial code provided sets only single pixels to illustrate the starting point.
- The goal is to understand the internals of 3D graphics libraries, not to write GPU applications, and the author provides the complete source code on GitHub.
