Many 3D shapes generated by 3D computer software consist of polygons. Simple geometric shapes can be defined by dozens of polygons; Objects that need a lot of details, such as tea cups, need hundreds of polygons to form details. Complex objects, such as a detailed mannequin, may need thousands of polygons.
Models of natural phenomena may require millions of polygons. A polygon can be identified as an edge. Traditionally, how many polygons a three-dimensional model has is called how many faces it has, that is, how many faces the model has.

Types of noodles:
1, geometric shape: also known as inorganic shape, is a curved surface composed of straight lines, curves or straight curves by mathematical methods. Such as special rectangle, square, general rectangle, triangle, trapezoid, diamond, circle, pentagon, etc. , with mathematical simplicity, lightness, composure and sense of order, is widely used in the modeling design of buildings and practical utensils.
2. Organic form: it is a biological form that cannot be obtained by mathematical methods. It is rich in natural development, with a sense of order and regularity, with the rhythm of life and simple visual characteristics. For example, pebbles, maple leaves, biological cells, melon and fruit shapes and human eyes in nature are all organic.
3. Accidentality: refers to a natural or man-made accidental form, the result of which is uncontrollable, such as ink or water spilling or dripping, insect eyes on leaves, accidental tearing of paper, etc. , with unrepeatable contingency and vitality.
4. Irregular: refers to the free form created by man, and can use all kinds of free and freehand linear forms at will, with strong modeling characteristics and distinct personality.
