Computer graphics (CG) and mathematics have a strong connection. For instance, generating geometric shapes like curves and spheres, as well as performing shape operations such as translation, scaling, and rotation, are all reliant on mathematics. Especially in CG production methods that leverage mathematics, such as procedural graphics and algorithmic design, enhancing one's mathematical skills can significantly expand creative possibilities. Moreover, applying mathematics in CG can deepen one's visual understanding of mathematical concepts. In this lecture, we will explore the relationship between CG and mathematics from both perspectives.
