What is the process called when converting an image stored by a geometric formula into pixels?

The process of converting an image that is represented by geometric formulas into pixels is known as rasterization. This transformation takes vector-based graphics—which are composed of mathematical equations that define shapes, lines, and colors—and converts them into a raster image format, consisting of a grid of individual pixels. Each pixel holds specific color information, thereby allowing the image to be displayed on screen or printed. Raster images are resolution-dependent, meaning they can lose quality if scaled up.

Understanding this concept is essential in graphic design and digital art, as it highlights the fundamental difference between vector and raster graphics. Rasterization plays a crucial role in how images are rendered in software applications, enabling smooth visual output for images that were originally defined by curves and lines.
