What is 3D modeling? Types, and a complete guide

Have you ever wondered what is 3D modeling which shapes numerous things in our daily lives? We have all probably profited from this kind of technology in some way, whether in the gaming field or architecture. Here, we find out the complex nature of 3D modeling and all the benefits it offers.

What is 3D modeling?

3D modeling definition

The technique of creating a mathematical representation of any item surface in three dimensions using specialized applications is the definition of 3D modeling. This illustration refers to a model which is the work of a 3D artist.

Early in the 1960s, computer graphics were used for engineering and scientific applications for the first time. Following this milestone, by the late 1960s, CGI was being used for creative expression. And Syntha Vision, the first solid modeler program was sold commercially in 1969. NURBS and parametric modeling, which gave rise to Pro/ ENGINEER, did not appear until the next 20 years. 3D modeling has expanded in recognition and efficiency, with utilization in countless things, from games and movies to all sectors of commercial design and production. Then, Stereolithography (SLA), the original 3D printing technology, initially appeared in 1986 and is the name of today's well-known STL file.

Type of 3D modeling: how do they work?

There are a few general types of 3D modeling methods when discussing the explanation of 3D modeling categories.

• Polygonal modeling: a representation of points in 3D space combined by line segments to create a polygon mesh. Planar files for polygonal meshes are represented by a collection of flat facets. Hence, curves can only be precisely estimated as a result of using surface subdivisions with a specified resolution. Because they are lightweight and generate visualizations quickly, polygonal meshes are useful.

• Curve modeling: uses curves to produce surface geometry. Designers apply NURBS (nonuniform rational B-splines) to both parametric and freeform curve modeling to define surface forms. They use weighted control points to modify the mathematical equations driving the curves.

• Digital sculpting: a relatively new method of 3D modeling in which the user manipulates the digital object like they would model the clay. So as to produce their models, users can push, pull, pinch, or twist virtual clay.

• Code-driven modeling: a developing branch of modeling where the designer sets conditions and the geometry is generated on its own. This is an ideal modeling approach for 3D printing since it can produce 3D structures that cannot be produced in any other way.

What is 3D modeling used for?

Gaming industry

The creation of games may be the most common usage of 3D modeling. The process of using 3D models to generate characters, environments, objects, and entire universes is the answer to what is 3D designing in this entertaining form. Also, immersion is the key to every successful game, and 3D modeling is a perfect solution.

In terms of virtual reality gaming which is a very fascinating industry, 3D modeling is especially crucial. By building entire three-dimensional environments which allow you to explore, virtual reality games completely submerge you in the gameplay.

3D printing

It is clear that 3D modeling is necessary for 3D printing. 3D models may be turned into tangible objects via 3D printing, which can be utilized for everything you can think of. There are several practical applications for 3D printing that go far beyond the small figurines and toys produced by home printers.

After getting to know the 3D modeling description, people found out that this technology has a profound impact on patients' lives. Therefore, it is widely used in healthcare. The purpose of using this 3D skill is to construct specialized implants and prosthetics as well as anatomically accurate models for surgical planning. 

Architecture

Architecture is another profession frequently applying 3D modeling. With the advancement of technology, we can now visualize a building in three dimensions even before it is completely constructed instead of hand-drawn building designs.

This is incredibly helpful for other stakeholders as well as for pitching the final product. Therefore, modern building design relies heavily on 3D modeling. It can show possible problems with building structures that 2D plans could not.

Animation

So what is 3D modeling application to animation? Once people have a 3D model, they can fully rig and animate it. This step greatly enhances the effectiveness of animation. To achieve a seamless, consistent effect, animators use 3D models in the production of films and television shows. 3D modeling appears throughout every stage in the creation of scenery, characters, props, and much more.

Product design

A number of things that we use on a daily basis likely involve 3D modeling. Prior to actual production, we may identify any flaws and correct the product by developing its virtual 3D model version. This edition of the product provides an overview of how big the object is in comparison to other goods, resulting in a significant impact on the manufacturing process.

It is helpful for pitching product ideas to investors as well, because things can be represented from all angles. The design allows the stakeholders to completely visualize the finished product. Also, it is less wasteful than continuously building fake products and creating samples.

Types of 3D modeling method

Parametric modeling

When talking about parametric 3D modeling meaning, this kind significantly depends on the object size (width, height, breadth, length). It is used to create or design items like a cube, a mount for a robot motor, an automobile, or even a jet, all of which must adhere to precise size/ parametric requirements. Here, the design process prioritizes precision measurements; and quick design changes are allowed. Consequently, parametric modeling is excellent for projects relating to strict specifications and manufacturing needs. And industrial designers frequently use it in the design and production of products.

Polygonal/ direct modeling

Concepts, not measurements, drive this 3D modeling method. It's comparable to creating something out of clay, where the final product is more dependent on artistic vision than predetermined measurements. It emphasizes intellectual thought and resembles molding digital clay to develop or design 3D objects, such as CGI (computer-generated imagery) movie characters and video game characters. Additionally, it is often utilized today in the animation and video game industries. Here, improvisation is more vital than measurements, unlike in parametric modeling. Today, most 3D models are created as textured polygonal models since they are flexible and rendered quickly on computers.

What is 3D modeling first step to learn?

After having basic knowledge about 3D modeling overview, your first 3D work will be heavily influenced by where and what you learn. To begin with, something simple is always a smart idea, though. Thoroughly learn the fundamentals and get used to the software you are using. Eventually, you will ramp up the pace and start producing complete 3D models of anything you like. Once you understand the fundamentals, you might also experiment with the software to see if you can create a personal project.
