Polygon rasterization with edge function
Webpgon = polyshape (P) creates a polyshape from the 2-D vertices defined in the N -by-2 matrix P, where N is the number of vertices. The first column of P defines the x -coordinates, and … WebRasterization. After the vertex processing stage, the rasterization stage converts the transformed vertices into a set of pixels that represent the surface of the 3D models on the 2D screen. Rasterization involves generating fragments, which are small pieces of a triangle or polygon that represent the area covered by the primitive on the screen.

WebRasterization produces a series of frame buffer addresses and associated values using a two-dimensional description of a point, line segment, or polygon. Each fragment so produced is fed into the last stage, per-fragment operations, which performs the final operations on the data before it's stored as pixels in the frame buffer.
