Where is the site about computer graphics?

Question

Algorithms

I have many questions, such as how to build Corel Draw yourself. For example, come up with an algorithm for dividing polygons, merging polygons, cutting, etc. Of course, I don’t do corel draw myself, but I have a similar program (2D CAD). And all sorts of questions constantly come out ... Is there an intelligent website, blog, material, book on this topic?
