The graphics pipeline takes vertices as input and processes them through different stages to produce pixels as output. It first processes vertices through the vertex shader, then assembles them into primitives through primitive assembly. It rasterizes primitives to produce fragments that are processed by the fragment shader to yield pixel colors, which are then blended and undergo post processing effects before final display.
