Best Modeling Paradigm, Pedigree extends back decades

IN 3d Modeling _Polygon is a 3d mathematical construct composed of three or more sets of points having X,Y,Z coordinates in 3d space. These points not only have positional values, they are also connected in a particular order, Which determines the way the polygon is said to face. This facing direction  is shown by a polygon's surface normal.
                                        IN 3d Polygons are the best modeling Paradigm: their pedigree extends back decades. Nearly supplanted by Non Uniform Rational B-Spline (Nurbs Modeling) for organic character work.In 3d services Maya's weakest of toolsets, the polygonal modeling tools have evolved into extremely powerful and versatile sculpting commands that allow the artist to create any form imaginable.

Polygonal Modeling Principles: In polygonal modeling we fellow several principle.

• Four side polygons,or quads as they will be referred to from  here on, are the best type of ploygons to use because they deform well. they convert to other types of surfaces well, and you can cleanly use many of Maya's editing tools on them.
• Never use more than four sided polygons, or n-sides polygons.
• Keep your model in a clean, quad- based topology while you are working ;this will save clean -up time at the end of the process.
• Delete history often.This prevents modeling slowdown from unneccessary nodes evaluation.
• Always model with construction history turned on.This will allow you to use the inputs to do some powerful editing after the fact, and adjusting the attributes of a node in the inputs list is often the fastest way to learn about a new feature.
