2D geometric model
A 2D geometric model is a geometric model of an object as two-dimensional figure, usually on the Euclidean or Cartesian plane.
Even though all material 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 computer graphics and often used as components of 3D geometric models , e.g. to describe the decals to be applied to a car model.
2D geometric modeling techniques
- simple geometric shapes
- boundary representation
- the brush-and-path paradigm
- Boolean operations (constructive geometry ) including clipping
