科技 Crash Course
Just like how characters were stored in memory and turned into graphics by a character generator, these vector instructions were also stored in memory, and rendered to a screen using a vector graphics card.
Vector graphics is the use of polygons to represent images in computer graphics. Vector graphics are based on vectors, which lead through locations called control points or nodes. Each of these points has a definite position on the x and y axes of the work plane and determines the direction of the path; further, each path may be assigned a stroke color, shape, curve, thickness, and fill.
