Graphics ProgrammingPrinciples and AlgorithmsZongli ShiMay 27, 2017 AbstractThis paper is an introduction to Graphics Programming . This is a computer science fieldtrying to answer questions such as how we can model 2D and 3D objects and have them displayedon screen. Researchers in this field are constantly trying to find more efficient Algorithms forthese tasks. We are going to look at basic Algorithms for modeling and drawing line segments,2D and 3D polygons. We are also going to explore ways to transform and clip 2D and 3 Dpolygons. For illustration purpose, the Algorithms presented in this paper are implemented inC++ and hosted at GitHub.
The basic problems in graphics programming are similar to those in any task of approximation. The notion of shapes such as polygons and lines are abstract, and by their de nitions, continuous in their nature. A line can extend to both directions forever. A polygon can be made as large as we
