Intermediate Topic 20 of 49 Graphics, Vision & Media
Rasterization
Converting geometry into fragments on a pixel grid.
How it works
Triangles are converted to fragments by testing which pixels they cover (edge functions), interpolating attributes with barycentric coordinates; it is fast and used in real-time rendering.
Where it is used
Games and UIs.
Common pitfall
Aliased edges require multisampling.
