In this video I cover some of the action that takes place at the end of the vertex level processing of the graphics pipeline. The focus is on clipping and viewport mapping and how they get us from NDC space to screen space pixels.

🔥 See the list of the books that I'm using as background information for my tutorials: https://ogldev.org/books.html. I highly recommend them for learning more about OpenGL and Vulkan. These are affiliate links so if you use them to buy any of the books the price is the same for you and I will get a small commission (thank-you!).
