### [Rasterization from Scratch: Drawing a Triangle](https://vec4.hashnode.dev/rasterization-from-scratch-drawing-a-triangle?utm_source=hashnode&utm_medium=feed)

What we're doing Last post: black window, nothing drawn. This post: a full-screen cycling color and a filled triangle — the first real pixels we write ourselves. Two new things added to the codebase:

### [Rasterization from Scratch: Project Setup](https://vec4.hashnode.dev/rasterization-from-scratch-project-setup?utm_source=hashnode&utm_medium=feed)

What we're building Theory is done. Now we write code. This series implements a software rasterizer — entirely on the CPU, writing pixels directly into a framebuffer. No OpenGL. No Vulkan. No shortcut

### [Rasterization from Scratch: How Triangles Become Pixels](https://vec4.hashnode.dev/rasterization-from-scratch-how-triangles-become-pixels?utm_source=hashnode&utm_medium=feed)

Why rasterization exists At some point, all rendering boils down to a simple question: Given a triangle, which pixels on the screen belong to it? GPUs answer this billions of times per second. But t
