Evolution of PC Graphics Rendering Pipeline: From Fixed‑Function Era to Real‑Time Path Tracing

The visual fidelity of PC video games has surged dramatically over the last thirty years. Early titles relied on simple, purpose‑built hardware that rendered only a few textured triangles. Today’s graphics pipelines, however, are fully programmable and massively parallel, enabling real‑time simulations of light, materials, and geometry with physical accuracy that was once exclusive to offline film production.

At the core of this transformation lies the graphics rendering pipeline-a concrete, implementable sequence of stages that takes 3D data and converts it into the final pixels you see on your screen. Although often discussed as an abstract concept, the pipeline is the actual engine driving every frame in modern games.
