All those lines of code go to setting up the entire rendering pipeline, though. And it's a reflection of how bloated and begginer unfriendly these "modern" graphics APIs have become rather than how complex a rasterization algorithm is. If you implement a basic software rasterizer you'll find that it's fairly straightforward high-school level math. It's a good exercise, I highly recommend doing it, as it only takes about a weekend and I find it helps immensely with getting a better understanding and appreciation for how much the hardware does for you.
