primitive assembly
The pipeline stage that groups individual vertices into the actual shapes (triangles, lines) to be drawn.
After vertices are processed individually, primitive assembly collects them in the right groupings — every three vertices into a triangle, for example — to form the primitives the rasterizer will fill. It sits between vertex processing and rasterization in the graphics pipeline. This stage also handles rules like primitive restart that decide where one shape ends and the next begins.
