scanline rasterizer
The engine that turns triangles and shapes into pixels by filling them one horizontal row at a time.
Rasterization is the step that decides which pixels a geometric primitive covers. A scanline rasterizer processes each shape row by row (scanline by scanline), computing where the shape's edges cross each row and filling between them. It is a well-understood, cache-friendly approach and forms the heart of many CPU software renderers.
