3D modeling has become an important part of our lives, starting from the entertainment and gaming industry to building homes and visualizing the shape of products. With the continuous development, the types of modeling have become different, and each type has its own use. The following is a comprehensive guide about this term and its most important types.
What is 3D modeling?
A 3D model is a digital twin of an object in three dimensions and is a digital file created using a specialized software program or through 3D scanning. 3D modeling is the process of converting two-dimensional images into a 3D file as a digital twin of an object using 3D modeling software, such as Matterport. In general, there are 3 types of 3D modeling that are explained in detail in the following lines.
Types of 3D Modeling
There are three main types of 3D modeling, which are as follows:
Solid modeling
Solid modeling is the cornerstone of 3D modeling, and can start with 2D or 3D shapes or basic geometric shapes such as cubes, spheres, cones, and cylinders. These shapes form a variety of geometric shapes and the designer can manipulate these blocks or transform them into a more complex shape.
Solid modeling is not limited to providing a 3D model of an object, it is particularly accurate in terms of dimensions and angles that enable computer analysis and digital prototyping, and is therefore widely used in engineering and manufacturing where accuracy in measurements is very important.
Advantages of solid modeling
- The tools or software used in solid modeling technology are not complex and will not require extensive training to understand.
- Creating 3D solid modeling does not require high-spec equipment.
- The final output has high dimensional accuracy similar to the real-world model.
Disadvantages of Solid Modeling
Although solid modeling is mathematically accurate, the end result may look a bit rigid and out of touch with reality.
wireframe modeling
The second type of modeling is wireframe. The term is inspired by the use of "metal wire" to represent the 3D shape of a solid object. Basically, there are no visible surfaces in a wireframe model, and even the internal components or basic designs are visible. This echoes the skeletal framework of a 3D object that is built by connecting each point called vertices with lines or curves.
In wireframe modeling, the triangle is the basic polygonal element. A wireframe model is created by connecting each vertex to a line segment called an edge which can be either a straight line or a curved line thus creating a face. Each geometric face consists of at least three vertices which can be part of one or more vertices. The shape and size of the model are modified by changing the position of each vertex.
Advantages of wireframe modeling
Because wireframe modeling creates a 3D model by connecting vertices with lines, the result will be more complex surfaces and curves than solid-looking 3D models.
Disadvantages of wireframe modeling
Creating a 3D wireframe model requires some training and higher hardware specifications because it produces higher resolution graphics.
surface modeling
Surface modeling is the most advanced type of 3D modeling, it is more complex than wireframe modeling but not as sophisticated as solid modeling.
Surface modeling produces smooth and complex surfaces, and unlike solid models, they cannot be sliced open and may be geometrically incorrect because the use of this modeling technique aims to focus on the visual representation of the exterior of the body and its surroundings, this gives the designer the freedom to design the 3D model since dimensional accuracy is not exactly an issue.
This 3D modeling method is widely used in illustrations, architectural drawings, 3D animation for games and other presentations.
Advantages of surface modeling
It is a type of modeling that helps in designing smoother and more complex surfaces, making it more realistic, which is especially preferred in industries such as architecture, automobiles, and aircraft.
Disadvantages of surface modeling
Since this technique is more complex, it requires higher skill in graphics and advanced software or programs.
Uses of 3D modeling of all kinds
All types of modeling are used in a number of different industries and sectors such as entertainment, video games, modern construction, and
Fashion, healthcare and decoration, it helps in visualizing the product or building before it is actually built, which reduces errors.
All industries see this technology as important and greatly helps in the success of the project as it allows the creation of everything from characters and products to landscapes.
Modeling is also used in presentation or simulation, which may represent a very good basis for many fields. For example, an architect plans and designs work through modeling.
Different types of 3D modeling have also become an important part of manufacturing processes, saving time and money, while improving products and processes.
