• A polygon is a collection of fundamental geometric entities, each of
which is composed of vertices and straight edges.
• A vertex is the tiniest component of a polygon.

• An edge is the intersection of two polygonal facets on the surface of the
polygon.
• A mesh is a three-dimensional model composed of vertices, edges, and
faces that define the form.
• A face is an area that has three or more edges enclosing it.

Wireframe, surface, solid, and 3D sculpting modelling are the four fundamental
forms of 3D development. Wireframe modelling utilises edges and vertices to
depict solely the fundamental structure of an object or character. In contrast,
surface modelling displays the surface texture, shading, and colour of a 3D model
through a polygonal mesh. Solid modelling represents the interior and exterior of

the 3D-modelled object, surpassing mere surface representation. Ultimately, 3D
sculpting, also known as polygonal modelling, adds intricate textures and details
to the polygonal geometry of the 3D model.

Wireframe modelling Solid modelling

The elemental 3D modelling workflow consists of the following stages:
conceptualising, modelling, texturing, shading, rigging and animation, and effects.
The stage of conceptualising involves thinking through the object that is to be

created, following the logical sequence of a storyline. At this point, making a
storyboard is essential. This is a sequential arrangement of the photographs that,
in accordance with the script, will eventually be turned into 3D models in one of
the subsequent phases.
