3D models are becoming more and more popular. First of all, they are of great use in most of spheres of human life. For instance, 3D models are indispensable in entertainment industry, science, as well as business. Small wonder! With the advancement of technology, they increased in variety and got cheaper.
Most noteworthy, 3D is popular not only among large companies with huge investments. What is more, models are also largely used by small family businesses.
Need 3D models for your business? Then you might also need to learn what 3D modeling process is. For knowing its intermediary stages and products will help you to optimize the work process and get better and faster results.
However, the incredible variety of 3D models on the market nowadays can be confusing. Especially if you are new to the sphere and need to make the right choice.
So, you too are feeling lost in this ocean of information about 3D models? Trying to figure out its uses and advantages for your business?
To help you with that, we organized this information and created a classification. It contains the most popular categories of 3D models. What are they? Read below!
Criterion 1: 3D Models according to the Level of Detail
1.Polygonal 3D Models
3D model of this type consists of a certain amount of polygons. The term “polygons” are primitive geometrical shapes with 3 or 4 sides.
1.1. Low-poly 3D Models
It is created through simplified carcass modeling. Most importantly, low-poly 3D don’t transmit detailed information about the object. For instance, it says nothing about the surface structure. The main advantage is that its creation doesn’t require a lot of memory. You can find this kind of 3D models in computer games, applications and animation.
1.2. High-poly 3D Models
This type of 3D model is created by thorough development of surface, texture, with finest details. The main point of 3D modeling of this type is that it helps us to get photorealistic images. However, it requires pre-rendering of the image. If you wish, you can learn more about our 3D rendering services.
Most noteworthy, cinema and architecture use 3D models of this type.
2. NURBS 3D Models
NURBS stands for Non-Uniform Rational B-Splines. The surface of a NURBS model consists of points connected by a predetermined formula. Importantly, models of this type are more accurate. They are used by engineers, mechanical engineers and architects.
For better understanding, let’s turn to the difference between raster and vector graphics. This way, polygonal 3D models are raster graphics, while NURBS 3D – vector graphics. You can zoom vector graphics all you want – the lines will remain smooth. However, with raster graphics, that’s not the case.
Criterion 2: According to Techniques of Prototyping
To create a physical prototype, a high-quality model is required. In addition, it must contain all data about the object: lines, edges, texture, volume, mass.
1. 3D Model for Production on CNC Machine
To begin with, such machine can produce 3D model object of any complexity. Furthermore, the process is based on the milling. That is, the object is cut out according to 3D model. The method has existed for more than a century! Nowadays, it is used for creation of jewelry, souvenirs, furniture and decorative elements, weapons, equipment, etc. Nevertheless, there are limitations: such machines may not work with all materials.
2. 3D Model for Printing to a 3D Printer
Printing on 3D printers is a new cutting-edge technology. However, it’s becoming more popular day by day. As for the technology, it consists in laying down successive layers of plastic. The best thing about 3D models for 3D printing is that they allow you to print anything! For example, human organs and prostheses, souvenirs, furniture, industrial purpose machines. Just imagine: using a 3D printer, you can even “print” a house or other architectural structures of any complexity.
Criterion 3: By Type of Objects of 3D Modeling
You can create 3D model of almost anything. Sky is the limit! There is a wide variety of 3D models and objects. With 3D being used in different spheres, categories of 3D models were formed. The most popular ones we presented in the table below.
|Category||Examples||Spheres of application||Advantages of the 3D model type|
|Owing to 3D models, we met Hulk, Iron Man and Sheriff Woody from Toy Story|
To conclude, 3D models give humanity a great opportunity to create any object in 3D and prevent errors during design process. Without exaggeration, 3D opens up new horizons for all of us. For we can not only create a 3D model, but simulate any real situation as well.
Creation of 3D models has turned into a separate industry that continues to grow. Moreover, there are real 3D stock markets, where you can purchase a 3D model you liked, as in a usual online store. Furthermore, if you need a model to order, you can turn to specialized companies. Click and learn how to choose 3D modeling services provider wisely – read the expert opinion.
