The advent of computing power, programmability, storage, and graphics displays in the late 1950s and early 1960s marked a significant turning point in the development of computer graphics. As these technologies became available, techniques that were previously mechanical, such as using templates, could be replicated on computers. One notable example is the generation of conic sections, which are families of 2D curves on a flat surface. Curves play a crucial role in various design fields, including aircraft, automotive, shipbuilding, appliance design, architecture, bionics, and sports. Computer-aided design (CAD) was one of the first applications to leverage computer-generated curves and surfaces, and it undoubtedly became the first commercial application of its kind. As designs became more sophisticated, the need to add color arose, and the 1970s saw a surge in the development of surface shading and mapping techniques. Furthermore, image filters became essential for refining generated images, smoothing out lines, and reducing blurriness. Given that we inhabit a 3D world, it’s only natural to want to capture its essence in art. This chapter has explored the algorithmic aspects of computer graphics, revealing that CG is built upon a collection of clever tricks designed to create the illusion of reality. These techniques don’t aim for absolute accuracy but instead strive to create a convincing visual experience, often relying on the viewer’s suspension of disbelief to bridge the gap between what’s real and what’s rendered.
