What Does Vector Graphics Rendering Mean?

Vector graphics rendering is the process of generating models from geometrical primitives such as lines, points, curves and shapes to represent images in computer graphics.

Techopedia Explains Vector Graphics Rendering

A point is defined in space (either two or three-dimensional) by a combination of the angle of the point from the zero plane, the z-dimension (in 3D graphics) and the distance of the point from the origin. This makes the definition of shapes using vector geometry a mathematical formula rather than a fixed data array that defines bitmapped images.
