Modelling and Rendering a surface

Common practice in modelling and rendering a surface is to approximate it by a polygonal surface.  By a polygonal surface we mean a surface which is made up of polygons.  Main reason for converting a surface to a polygonal surface is to simplify representation for speeding up the surface rendering. This is possible as all the polygons are described by linear equations.
