What is 3D Modeling? 

3D modeling is a technique to build or create 3D objects virtually by forming, deforming, and manipulating the vertices, polygon, edges vertically and horizontally using coordinate representation in specialized 3D modeling software. 

3D modeling can be operated manually, algorithmically (procedural modeling), and scanning. 3D modeling allows us to create designs or models that are impossible to generate in real life. 

A specialist uses 3D modeling software to create the desired object in the virtual world of 3D software by manipulating vertices, polygons, triangles in the coordinate space of 3D software to form a mesh or physical appearance of an object. It can be changed either manually or automatically by modifying or manipulating vertices. 

3D modeling has extensive use from small to large-scale industries, gaming, animation, movies, architectures, 3D tours in real estate, academic research, etc. 

The basic core operation of 3D modeling shapes can be made by joining points to points in coordinate space. These points can be joined together to form a 3D grid and shapes of 3D  triangle polygon quadrilaterals. We can combine these complex 3D figures to create the desired outcome by manipulating their figure. 

Uses of 3D Modeling 

Since 3D modeling took foot in the world, its demand has increased day by day. From academic research to planning a building, gaming, engineering, industries, 3D printing, laser cutting and engraving etc., 3D modeling plays a pivotal role in giving outcomes more accurately than other conventional methods. 

There are multitudes of uses of 3D modeling; some of them are discussed below. 

3D modeling is a pervasive form of technology; many industries use this technology for various purposes. Some of them are:  

  • Building planning by using architectural visualization  
  • 3D image in the field of real estate 
  • Video games and movies creation 
  • Research purposes

We will discuss some of the uses of 3D modeling in various fields in detail. 

  1. Interior visualization: This technology is booming in this field as many users are using it in the interior design of their homes. 3D modeling creates the interior of the building before using actual objects such as furniture, frames, etc. 
  2. 3D printing: Initially, it was a slow-growing technology, but after knowing its benefits and ease to use, it is growing at a good pace. This technology can be used for creating a prototype of a design before printing it for the actual purpose. Since prototypes can easily be built, some tools can also be created. This technology has endless possibilities.
  3. Media: From film to gaming industries as well as in publishing, the use of 3D modeling is extensive. Special effects in movies and games can be created using this technology. Any character that you can imagine can be created using this technology. In publicizing new products, this technology is widely used as well.
  4. Measurement: Because of this technology, there is no need to carry those measurement tools with you. 3D design can easily show the object’s dimensions that you want to measure. This can help the user decide what size of furniture he needs for this home.
  5.  Engineering: Last but not least, 3D modeling is widely used in various ways by engineers in numerous applications. This technology can create a 3D replica of any object that it can scan. This will help the engineers to understand the machines better.

Advantages and Disadvantages of 3D Modeling 

Producers across industries worldwide are in the rat race to increase the productivity level. The Birth of new technology can give another lead in the competition. Due to this, many companies are entirely transitioning from conventional methods i.e., 2D to 3D modeling. 

Compared to 2D modeling, 3D modeling works with high accuracy and is cost-effective. In many areas where 2D modeling doesn’t ingress or adopt itself,3D modeling comes with great accessibility and understanding.  

So if you are an architect, industrialist, or manufacturing engineer and want to design swiftly and efficiently, then it’s time to switch to 3D modeling. 

Fast designing process: In industries like manufacturing and designing, time is as valuable as money, so this is the crucial reason why companies turn over to 3D modeling to rule the roost in their competition. 

3D modeling is quick compared to other conventional methods where you have to produce at a fast pace.  

Easy to access design: The essential feature differentiating 3D modeling from other conventional methods is time effectiveness, but that doesn’t mean its efficiency or manufacturing deteriorates with time. 3D modeling enables us to access complex designs efficiently. Whenever needed, you can create 3D models quickly. 

Data management with effectiveness: 3D modeling is well-equipped with efficient data management. In 2D modeling, designers have to record their data manually. Managing information accurately is always a concern, especially in complex design. 

3D modeling software allows you to keep and manage your data automatically. In 2D modeling, designers have to update BOM(bill of material) after every single design, but the software automatically updates it in the case of 3D modeling. Due to this, it is easy to manage data of complex structures. 

Device control:3D modeling provided us with more accurate and precise device control. Device or machine can be guided expeditiously based on 3D model measurement without using conventional survey stake. 

GPS can set up machines like bulldozers or heavy appliances with a 3D model. Models can automatically be set up by sensing their surface depths or elevation. 

Disadvantages of 3D modeling 

3D modeling demands are increasing day by day with new advancements in technology, and this is going on. However, it comes with some disadvantages, as mentioned below:

  • A specialized team is required with suitable training to cope with market demands. 
  • The tools of 3D modeling need expensive hardware to process. 
  • Extensive computational skills are needed.
