What is 3D modeling?
3D modeling is the process of using software to create a mathematical representation of a 3-dimensional object or shape. The created object is called a 3D model and these 3-dimensional models are used in a variety of industries. The film, television, video games, architecture, construction, product development, science and medical industries all use 3D models to visualize, simulate, and render graphic designs.
Common types of geometry in 3D modeling
Polygons are straight-sided shapes, defined by 3-dimensional points (vertices) and the straight lines that connect them (edges).
Modelers who use polygons usually use 3-sided polygons called triangles or 4-sided polygons called quadrilaterals.
Polygonal surfaces have a wide range of applications and are the preferred surface type for animated effects in film, video game design (US site), and 3D web development.
Curves and NURBS modeling
NURBS, which stands for Non-Uniform Rational B-Splines, are composed of curves and are defined by a mathematical formula.
NURBS are best used for modeling smooth surfaces with complex curves, such as a wineglass or a football.
