3d modeling

The main types of 3D modeling

3D modeling is the process of creating a 3D representation of an object, surface or person. It is a question of taking into account the three dimensions: length, width and depth. 3D models can be created for various purposes, such as architecture, engineering, product design, and video games. There are a few main types of 3D modeling: polygonal, solid, and surface modeling, and a few others. In this article, let’s look at them and also used software licenses more in detail.

In which fields is 3D modeling used?

The creation of three-dimensional models is used in various fields:

  • Architecture and construction — for the development of projects, the evaluation of buildings, the calculation of their stability;
  • Medicine – for creating organ and tissue models, planning operations;
  • Industry – for the production of three-dimensional prototypes of products before starting mass production, as well as for advertising purposes;
  • Art and entertainment – it is widely used in the film and game industry.

The number of areas in which three-dimensional modeling can be used is constantly increasing, as it is a very convenient and fast way to create a model of any object. So, let’s move on to the main types of three-dimensional modeling.

Polygonal modeling

It is considered the most common type. This type uses polygons as the basic building blocks. A polygon is a two-dimensional (2D) shape with three or more straight sides. To create a 3D model, several polygons are put together to form the surface of an object. Polygon modeling is sometimes also known as mesh modeling.

The advantage is that it can produce very detailed models. However, the downside is that it requires a lot of processing power to render these models and therefore may not be suitable for real-time applications such as video games. Some common software packages used for polygon modeling include 3ds Max, Maya, and Blender.

Solid modeling

It is the creation of objects in the form of solid forms. In other words, it is about creating a three-dimensional model of an object from its two-dimensional representation.

Solid models can take into account factors such as weight and stresses, which are important for engineering applications. Thus, solid modeling is typically used for engineering purposes, such as when designing parts for machines or vehicles. Models are often used in conjunction with polygonal models to create a complete image of an object. Some of the most popular solid modeling software include Autodesk Inventor, SolidWorks, and PTC Creo.

Wireframe modeling

It is one of the simplest types of 3D modeling. As the name suggests, it involves creating a model using only wireframes or lines that connect at points. This type is often used for conceptual purposes, such as when designing a building or machinery. It can also be used to create basic models that will be fleshed out later using another type of modeling.

The advantage of wireframe modeling is that it is relatively easy to create and modify. It is also very efficient in terms of processing power since there are no complex surfaces to render. For these reasons, it is often used for the early stages of the design process or for applications where processing power is limited. Some common wireframe software packages include Rhino 3D and SketchUp.

Surface modeling

It is the creation of three-dimensional models by working with NURBS surfaces. NURBS are mathematical representations of curved surfaces that can be used to create very smooth and precise shapes. Surface models are often used in product design because they allow you to create complex organic shapes that would be difficult to create with other types of 3D modeling. Some popular software includes Rhinoceros 3D, Alias ​​Wavefront, and CATIA Surfacing.

Box modeling

It is a type of creating a pattern by combining basic geometric shapes. The most commonly used shapes are cubes, but other shapes such as cylinders, spheres and cones can also be used.

Box modeling is often used for character design. Its advantage is that it is relatively easy to create complex shapes. The downside is that it can be difficult to control the overall shape of the model, and so this method is not always suitable for creating accurate models. It is relatively easy to learn and use, making it suitable for beginners. Some common software packages used for box modeling include 3ds Max, Maya, and Blender.

3D sculpture

3D sculpting involves shaping a model by adding and removing material in the same way a sculptor would work with clay. The advantage of 3D sculpting is that it can produce very organic shapes. However, the downside is that it can be difficult to get accurate shapes with this method. Some common programs used for 3D sculpting include ZBrush and Mudbox.

CAD software for 3D modeling

In order to create a 3D model, you will need specialized software capable of generating it. With the used software licenses that you can buy in the ProCadIs online shop, you can use all common CAD programs.

There is a wide range of software available for 3D modeling. The type of software you use will depend on the type of model you want to create and the purpose of the model.

For example, if you want to create a detailed polygonal model for a video game, you will need to use a powerful program such as 3ds Max, Maya, or Maxon Cinema 4D. However, if you just want to create a simple wireframe model for prototyping purposes, a less complex program such as AutoCAD, SketchUp or Rhinoceros 3D will suffice.
