A 2D geometric model is a geometric model of an object as a two-dimensional figure, usually on the euclidean or rial objects are three-dimensional, a 2D geometric model is often adequate for certain flat objects, such as paper cut-outs and machine parts made of sheet metal
2D geometric models are also convenient for describing certain types of artificial images such as technical diagrams logos, the glyphs of a font etc. They are an essential tool of 2D computre graphics and often used as components of 3Dgeometric models, e.g. to describe the decals to be applied to a car model. Modern architecture practice "digital rendering" which is a technique used to form a perception of a 2-D geometric model as of a 3-D geometric model designed through descriptive geometry and computerized equipment.
2D geometric modeling techniques
- simple geomatric shapes
- boundary representation
- boolean operations on polygons
