What is 3D Modeling?

3D Modeling represents an essential phase in the development of a three-dimensional asset. After selecting an object, it’s crucial to gather ample information for its construction. This typically involves collecting images and details regarding the size and functionality of each component. Once that groundwork is complete, it’s time to craft the model’s geometry—the 3D mesh. This can be achieved through 3D Modeling, Sculpting, or scanning techniques. It’s important to note that sculpting is a method of 3D Modeling rather than an alternative. Scanning provides a semi-automated approach to generating intricate geometries, which often require adjustments afterward. We will briefly explore each of these methods here.

2D vs 3D

To begin, let’s review the fundamentals. The term “3D” is widely recognized and typically refers to three-dimensional objects. The three dimensions encompass length, width, and height. Conversely, 2D pertains to a flat expanse featuring only length and width. You can differentiate between 2D (Shape) and 3D (Form) as illustrated in the image here. Adding a dimension of time (movement) results in 4D; however, we’ll delve into that topic in a future post.

3D Space

Now, let’s examine what a 3D space (three-dimensional space) entails and its representation within specialized 3D software. 3D space constitutes a geometric context in which the position of an element can be defined by three parameters (dimensions)—length, height, and width (x-axis, y-axis, z-axis). Models are generally constructed from polygons, edges, and vertices. Consider these as the foundational elements of the asset. Each plays an integral role in the model’s construction, and they are almost invariably interconnected.

3D Modeling

3D Modeling is the procedure employed to generate a three-dimensional representation of an object or form within specialized 3D design software. Once completed, this object is referred to as a 3D model, which can serve numerous purposes. For instance, 3D models find application in movies, games, augmented reality (AR), virtual reality (VR), 3D scanning, 3D printing, product design and manufacturing, as well as interior and exterior visualization, among others. Professionals offering 3D modeling services are known as 3D Modelers. Those specializing not just in Modeling but also in other facets of 3D art production—such as texturing, materials/shaders, lighting, rigging, animation, skinning, and fur—are recognized as 3D Artists.

3D Softwares

A variety of 3D software is available online (also termed 3D modeling programs). Depending on your needs, you may select software primarily designed for 3D designers, video game developers, animators, architectural visualization, product design and production specialists, etc. Excellent free 3D Modeling software options exist for beginners as well. Below, you can view statistics on the most popular paid and free software available.

Types of 3D Modeling

Numerous modeling techniques are present, but they all represent different avenues toward achieving the same goal: Box, Spline, Nurbs, Procedural, Sculpting, and Image-Based Modeling are among these techniques. Often, the endeavor of modeling a realistic 3D object necessitates a considerable amount of research and examination. If you are designing a real-world object, you will require images, blueprints, and measurements. Frequently, one or two of these essentials are lacking, complicating the 3D artist’s task. If you lack all three, you transition into the domain of concept or product design. Regarding the outcomes of the modeling process, various techniques can yield the same visual effects and results, sometimes through a combination of methods. The type of 3D Modeling also varies according to its intended usage. For example, 3D models utilized in movies, games, AR & VR, marketing, architectural renderings, and 3D printing all have distinct specifications and are not interchangeable. Each industry dictates specific requirements for the mesh (geometry) of 3D assets.

3D Modeling as a Service

With several major industries seeking 3D stock models, the demand for 3D modeling services has significantly increased over the past decade. Prominent freelancing platforms host numerous 3D artists searching for work and experience. However, for high-quality results on an important project, opting for a 3D studio’s services is advisable. The primary distinction between a studio and a freelancer lies in reliability and production capacity. A team of highly skilled 3D artists boasting extensive experience can tackle a diverse array of 3D projects, ranging from fundamental 3D modeling to the complex production of photorealistic 3D models. A studio can offer greater flexibility in accommodating your specific needs.

Why Use 3D?

No matter the technique employed to generate the 3D model, a lifelike 3D asset can be exceedingly valuable, particularly for producers, entrepreneurs, and designers. Here are several reasons why incorporating 3D Models might be beneficial, even if you’re not involved in the Gaming, Film, or AR/VR sectors:

• Enhance the showcasing of your product advantages.
• Elevate your sales with exceptional 3D visualizations.
• Surpass your rivals by providing your customers an intimate view of your product through 3D.
• *Enable your customers to picture your product in their surroundings or tailored to their specifications using 3D.
• *Conserve time by evaluating your product within a 3D environment.
• *Transform your concept into a tangible reality through 3D prototyping.
• *Display your product to potential clients or investors.
• *Develop your brand mascot or totem character.

Who Requires 3D Models?

Beyond the major sectors mentioned earlier, countless individuals and businesses globally use 3D to promote themselves, to manufacture, to design, to convey an idea or vision, and to gain an advantage in their niche. Numerous others are in need of 3D yet are unaware of it – including small business owners, students, and entrepreneurs.

How are 3D Models Being Utilized?

For over two decades, Hollywood has harnessed 3D to bring characters to life and narrate stories that are impossible to convey otherwise. The animation and gaming sectors are heavily reliant on 3D models for their settings, characters, and user interfaces. Architectural firms, apart from their CAD software projects, generate stunning photorealistic displays of their interior and exterior designs. They enable their clients to visualize their future homes long before construction kicks off. 3D printing and the technology around it are gaining traction, with applications ranging from toys and souvenirs on one end to 3D printed organs, vehicles, and houses on the other. Marketers around the globe utilize 3D models daily to highlight their products. Television stations incorporate 3D assets in news segments within VR studios as well as in corresponding infographics. The reality is that 3D is ubiquitous. A closer inspection will reveal it on television, social media, advertisements around your locality, and even in the products within your residence. Take any household item, and it’s highly likely that 3D played a significant role in its development, creation, and marketing.
