What is 3D modeling?

In three -dimensional computer graphics, 3D modeling is a 3D model development using specialized software. It is a process of creating a wire model model that represents a three -dimensional object. This object can be alive or inanimate. The three -dimensional model is created using a set of points in 3D space, which are connected by various geometric data such as rows and curved surfaces.

Three -dimensional models are created using four popular methods:

polygonal modeling . Many three -dimensional models are created as textured polygonal models. Polygonal modeling is a method of creating a 3D model by connecting the line segments via points in 3D space. These points in the space are also known as peaks. Polygonal models are very flexible and the computer can be rendered very quickly. However, it is not possible to create a precise curved surface using polygonal 3D modeling technique.

primitive modeling . This is the easiestModeling of three -dimensional objects. It is created using geometric primitives such as cylinders, cones, cubes and balls, complex models. This approach ensures easy construction because the forms are mathematically defined and accurate. Primitive modeling is mainly used in the development of 3D models of technical applications.

nurbs modeling . The NURBS modeling method can be found in popular software like Maya. The developer can create smooth volume 3D models using this modeling technique. Unlike polygonal modeling techniques, which can approximately approach curved surfaces with numerous polygons, NURBS modeling can actually create smooth curved surfaces.

spice and patches of modeling . These methods are similar to NURBS modeling procedures. Depends on curved lines to identify visible afterhill.

3D modeling can be easily performed using reserved software such as Maya, and 3DS Max. There are also some languages ​​of the description of the scene, such as the POV-Ray used for modeling. While most three -dimensional software suite is very high, open source programs are available for free. Most programs monitor the methods of modeling polygonal and NURBS to create models. For modeling complicated materials such as rain, clouds and sand blowing, programs use a particle system to facilitate the modeling process.

Today, 3D modeling is used in a wide range of activities. The video game branch uses different methods of three -dimensional modeling to create realistic character models for video games. In the field of medical field, detailed models of human body organs are created using different advanced 3D modeling software. The engineering community uses 3D computer design programs (CAD) to create three -dimensional models of new devices, vehicles andstructures.
