Hello, I just have a basic geometry question (really within the context of computer graphics). What is the significance in triangulating polygons? Why not squares, or polys with more angles? Why triangles? Is that because it is the simplest representation of a closed area? Also, is it due to trigonometric functions being able to operate on triangles? Are there similar functions in mathematics for rectangles, etc? I never took geometry in school, so now that I'm working with 3D graphics these questions are on the brain!(adsbygoogle = window.adsbygoogle || []).push({});
