2D Shape Primitives
You have already learnt to plot a point or a pixel on any display device. In this unit, we shall introduce you to various devices available for data input on graphics workstations and also study some of the basic algorithms that help create graphics output primitives. By graphics output primitives we mean the basic building blocks that are required to represent and model a real life object. For example, a four-leg table can be modelled using a few rectangular shapes and some curved 3D shapes (if required). Hence an output primitive is a simple geometric object that can be easily constructed and for which nice constructive algorithms exist. Some of the simpler shapes are lines, circles, ellipses, etc.
