DirectX 11/12 Rasterizer
A rasterizer for learning the rendering pipeline and DirectX. Implements four swappable shading models, debugged in RenderDoc, later ported to DirectX 12.
$ git clone https://github.com/XanderBert/DX-11-12-Rasterizer
This is a rasterizer built for the Graphics Programming course, aimed at learning the rendering pipeline and the basics of DirectX.
Setup
SDL handles window creation, surface management, and input events. DirectX handles rendering to the window and shader compilation. RenderDoc is used for graphics debugging throughout.
Shaders
I implemented four swappable shading models to compare how each one handles lighting and specular response:
- Cook-Torrance
- Blinn-Phong
- Phong
- Half Lambert

Adding DirectX 12 support
Later on I decided to learn DirectX 12 and the differences with DirectX 11. The biggest adjustment was DirectX 12’s much more explicit model: managing root signatures, command lists, and synchronization by hand, compared to how much of that DirectX 11 handles implicitly for you. I now have the same visual result as with DirectX 11, and I can switch between the render backends with a preprocessor statement. This project was purely a way to learn the DirectX 12 API, so no proper abstraction or switching layer between render backends was built here.
