What is 3D modelling?

3D modelling 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 visualise, simulate and render graphic designs.

Common types of geometry in 3D modelling

example of 3d modeling polygon primitives

Polygon modelling

Polygons are straight-sided shapes, defined by 3-dimensional points (vertexes) and the straight lines that connect them (edges).
Modellers 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.

example of 3d modeling NURBs primitives

Curves and NURBS modelling

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 modelling smooth surfaces with complex curves, such as a wineglass or a football.
NURBs are more widely used in industrial or mechanical design.

example of 3d modeling sub division primitives

Subdivision modelling

Subdivision surfaces possess characteristics of both polygon and NURBS surface types.
Like NURBS surfaces, subdivision surfaces are capable of producing smooth organic forms and can be shaped using relatively few control vertexes.
Like polygon surfaces, subdivision surfaces allow you to extrude specific areas and create detail in the surfaces when required.
