Before the computerisation and digitisation of work, creative designers and artists had to largely make do with paper and manual work. Then came Patrick Hanratty's pioneering  ‘PRONTO’ in 1957 and later on Ivan Sutherland’s revolutionising ‘Sketchpad’ in 1963. These important inventions and others helped establish computer-aided design (CAD), evolve more skills, and improve work processes.They also led to modern 3D modeling. But what exactly is 3D modeling?




3D modeling involves the development of a mathematical coordinate-based representation of a surface of an inanimate or living object in three dimensions with specialised software via the manipulation of edges, vertices, and polygons in a simulated three-dimensional space. In simpler terms, 3D modeling is the creation of three-dimensional objects on a computing device.

There are different 3D modeling techniques that can enable modellers to develop realistic and attractive models. Some of the most common techniques are:

Every modeling technique has its pros and cons, so selection should be based on degree of expertise and project goals.

3D modeling is a popular concept whose use cases and relevance spans several industries. Here are some examples:

Educators leverage 3D modeling techniques to provide instruction across multiple subject matter areas – from geometry to geology to geography. It enhances learner-teacher interaction by providing virtual models and simulations in environments that are safe and controlled.

There’s an extensive application of 3D modelling in films, TV programmes, music videos and video games. It is so entrenched that you’ll constantly see entire productions created with only 3D software. Prominent applications include areas such as computer-generated imagery (CGI) and visual effects (VFX).

3D modeling tools are used by architects and designers to construct virtual models of buildings, interiors and landscapes thus helping to communicate their ideas to clients, prospective investors, and others.

Automotive and Aerospace  

3D modelling plays a role in the design and testing of automobiles and their components. It enables auto industry professionals to develop realistic simulations which they use to evaluate an idea or an automobile and then use the feedback from the evaluation to make informed decisions.

Advertisers and digital marketers utilise 3D modelling to create compelling and visually appealing ad campaigns. Take the case of the automotive industry mentioned above. You must have seen vehicle and aeroplane ads made with 3D images that appear so realistic it becomes very difficult to differentiate them from real camera images.

The efficiency and eco-friendliness of 3D modelling when it comes to building prototypes, visualising product ideas and simulating pre-production functionality makes it a valuable asset in product design and manufacturing. It allows product designers to iterate continuously and modify ideas before manufacturing the final model of a product.

Health industry use cases of 3D modeling include surgical planning and medical imaging, among others. Using 3D models to accurately recreate tissues, bones and organs can enhance medical research, diagnosis of ailments, and treatment planning.

If you have little or no knowledge of 3D Modeling, learning it may seem daunting at first. But it doesn’t have to be so. By the time you go through the few tips below, you should be on your way to becoming a skilled 3D modeling pro.

Selecting a particular software from the many on the market should be based on variables such as modeling objectives, budget and skill level. Some widely used tools include Maya, 3dsmax, ZBrush, AutoCAD, and Blender. Be sure to conduct some research before settling for any product.

Even if you intend to pay for 3D modeling tutelage, it is a great idea to first have some basic knowledge of the concept. Here are some key basics to focus on:

The internet is awash with tons of free and paid resources that can help walk you through several aspects of 3D modeling. A good place to start learning is the website of the software you have chosen to work with. You can also watch YouTube videos and enrol in online courses. Formal tertiary education is also an option. While a DIY approach may work, opting to acquire knowledge from 3D modeling professionals has more advantages. Join some online 3D modeling communities to network and learn.

Practice Regularly     

It is said that practice makes perfect. Regular practice will enable you to consolidate and possibly add to all the knowledge and skills you’ve acquired.

As noted earlier, the application of 3D modeling cuts across industries. So if you work hard and acquire 3D modeling skills, then you will have significantly enhanced your chances of enjoying a successful career.
