Learning the Basic Terms in 3D Modelling

The introduction, application, and evolution of 3D modelling in different platforms and media formats presents an exciting prospect for graphic designers and artists. With 3D modelling, artists and designers can create, develop, enhance, and modify three-dimensional images through highly advanced, intelligent digital rendering software. This opens a universe of possibilities in various media – designs can be conceptualised, models can be created, entire worlds can be imagined, all through a single digital platform.

If you are interested in becoming a professional 3D rendering artist, here are a few of the basic concepts and terminologies that you must take to heart:

Polygon geometry

In elementary geometry, we were introduced to the concept of polygons – a plane figure that is composed of a determinate sequence of straight line segments that close in a loop. In 3D modelling, polygons are the most commonly used type of geometry. Roughly rendered models have fewer polygons, resulting in less realistic images. In order to achieve smooth, realistic, well-rendered imagery, more polygons are utilised.


Faces are the portions that are created when 3 or more edges of a three-dimensional polyhedral object are connected. This appears as the empty space between the edges of a polygonal mesh, helping define the shape of the polyhedral object in conjunction with vertices and edges. In a three-dimensional model, the faces are the spaces on which shading material is applied to apply distinction.


A vertex is a point where two or more curves, lines, or edges come together. Vertices are the smallest, most basic aspects of a polygon, but they are the fundamental building blocks of an entire polygon model. A polygon model can only achieve a particular shape by connecting multiple vertices together. To change the appearance of a model and achieve a desired shape, a designer must learn how to move and manipulate the different vertices of a polygon.


An edge is a line segment that connects a pair of vertices in a polygon, a polyhedron, or any other type of geometric object that is composed of flat sides. In 3D modelling, edges are key to defining the shape of a model, although modellers, designers, and renderers can also manipulate these aspects to modify the shape and appearance of an object.

It is important to master how you can apply and incorporate these basic aspects in order to grow your proficiency in 3D modelling. As you go along with your learning, you will encounter even more complex elements that will allow you to create more finely rendered digital images. But these aspects will remain the fundamental building blocks of your craft. To know more, visit this website today.
