It is a part of 3D graphics that deals with modeling the objects for 3D scenes. 3D modeling has its snags and rules. It is a skill that requires training and experience. An experienced 3D modelar can create a model of anything that exists in real life while keeping the required level of detail defined beforehand.

Several types of modeling techniques exist. Various techniques are used for various forms of modeling, e.g. for organic modeling or precise technical modeling. There are some rules of modeling and everybody who intends to make a living with modeling should be familiar with them. These rules are worth keeping. The reason might be to satisfy a client or provide a good quality model free of errors upon its subsequent thickening. A properly constructed model is always beneficial to the final solution. The result always depends on other criteria (used materials, composition, and illumination).

Professional 3D modelars pride themselves on clarity – correctness of the model. This is not professional deformation it is a necessity arising out of the efficiency dictate.
