3D: we’ve been hearing about it for a long time now. However, this technology has evolved so much in recent years that it’s taken our movie screens, our video games, our TV sets, and our advertising by storm. In short, it’s everywhere, and it’s so realistic that it seems increasingly accessible and easy to achieve. But how does it work? Let’s begin by demystifying the main step necessary for such true-to-life results: 3D modelling.3D modelling is the first step in 3D computer graphics. This imaging technique lets you create representations of objects in perspective. In a sense, the action of 3D modelling is the act of representing the objects that you want to visualize in three dimensions. For example, it lets you situate objects in space before manufacturing them. It can also be used to produce multimedia and audiovisual content. Starting from the simple shapes that define structures (curves, cubes, cones, cylinders, spheres, polygons, etc.), you can create characters, environments, more complex objects, and even very realistic renderings of existing spaces.

Computer-aided design (CAD)

It’s possible to represent just about anything with 3D modelling. By using one or more specialized programs, a graphic designer can apply characteristics to each of the elements that were first modelled (for example, texture or assembly) to make them more realistic and situate them in space. It’s even possible to move objects around and program their reactions.

What is it used for?

Of course, 3D modelling is essential in the video game and animated film industry, but it’s also used in many other fields. Since it allows for very specific designs of furniture and products, among other things, it’s very useful in the fields of set design, merchandising, and the automotive industry, as well as interior, commercial, and industrial architecture. In addition, it’s also highly valued in the fields of education and science due to its ability to virtually recreate the human body down to the smallest details, as well as many other phenomena.

Who can use 3D modelling?

The ability to create virtual worlds where your imagination is the only limit can be very attractive. More and more enthusiasts are occasionally indulging in it for the pleasure of discovering all the possibilities that 3D modelling offers at their own pace. A wide variety of different software is now available, from the beginner to the professional level. Increasingly simple and accessible, certain programs offer very interesting features. Patience, precision, and rigour are required to achieve excellent results. While for certain projects, drawing abilities aren’t essential, since you just have to follow the technical plans, creating realistic characters requires certain knowledge.

However, to make a job out of it, advanced knowledge is necessary. You’ll need adequate training and specialized equipment – in particular, a computer with an excellent graphics card. There are many modelling methods that may prove useful depending on the task to be completed (polygonal modeling, surface subdivision, geometry, curves, etc.).

3D modelling is essential these days, and it’s a very modern career choice. Very popular among fans of video games and animated films, it’s also very useful in many other fields of employment. Several establishments offer complete training, which will let you discover all its attractions. Don’t hesitate to get started in this field if you’re creative, patient, and able to work under pressure.
