Computational geometry is a branch of computer science devoted to the study of algorithms which can be stated in terms of geometry. (Wikipedia, CC BY-SA)
The main branches of computational geometry are: • Combinatorial computational geometry, also called algorithmic geometry, which deals with geometric objects as discrete entities. • Numerical computational geometry, also called machine geometry, computer-aided geometric design (CAGD), or geometric modeling, which deals primarily with representing real-world objects in forms suitable for computer computations in CAD/CAM systems. This branch may be seen as a further development of descriptive geometry and is often considered a branch of computer graphics or CAD. The term "computational geometry" in this meaning has been in use since 1971.
