The term 3D modelling is used to create eye catching and compelling graphics and images that have 3 dimensions. It is easy to make digital copies of things that are used every day, such as cars, machine accessories and parts and many other things. To create 3D models, you would need to have some coding knowledge and be proficient on 3D animation software programmes. You can also enlist the help of a reliable 3D modelling company if you are uncertain. 

The process of 3D modelling involves connecting a set of points with lines, curved surfaces and geometric data to thus create three dimensional models. Much like animation, 3D modelling requires you to have lots of skill, creativity, and imagination. This will ensure that your characters stand out from the crowd. People who are able to work well with a team and like putting ideas together with others will enjoy 3D modelling. 

Common Techniques Used  To Create 3D Assets For Gaming

Since the beginning of 3D modelling, the fact that it is visual has impacted on why it is such a big deal today. Whether you have knowledge of how it works or its flashy nature due to its artsy appeal, 3D modelling is becoming more well-known among people. 

3D Modelling Terms

In 3D modelling, there are a few must know 3D modelling terms that you should know and understand so that you will be able to communicate with clients and other designers efficiently.

Mesh: A collection of polygons and is available in a shape in the 3D field.

Vertex: The edge of a shape, and a point in space where edges meet.

Pole: A vertex with the edge protruding. 

Polygon: A face of a 3D shape that joins different vertices via edges.

Edge: A connection between two vertices.

Triangle: A polygon with three vertices.

Modelling Techniques

1. Image-Based Modelling – This 3D modelling method is also called three-dimension modelling straight from images. The technique involves using two-dimensional images to create three-dimensional figures. Often, these models contain a shape that may be geometrically formed and also include a texture map defining the shape. It is mainly used for entertainment, visual reality and robotics. The technique of modelling is used in situations where the modeller or 3D artist has a specific amount of time to successfully complete the project. 

2. Primitive Modelling – The advancement of modelling may be traced as far back as primitive shapes. They’re the building blocks of 3D modelling, and it is thus important that they are mentioned.  The most well-known 3D primitives are cones, pyramids, spheres, cylinders, and cubes. These are useful when sketching objects and also help you to create 3D models of those specific objects. 

There are so many software suites you can use as 3D designers. Primitive modelling is used to develop images of buildings and immovable objects, together with furniture. They are commonly used in the construction industry. 

3. Polygonal Modelling – you ever sat and thought about making a cube a room or plane or even something like a bottle of wine? You should consider the polygonal 3D modelling method if this is you. It is an advanced approach and it is used to depict an object by showing its surfaces making use of polygons. It is most often used to create 3D models for video games and movies. It is a good option to use and is ideal for real-time computer graphics. It makes objects appear even more real. You may already be aware that when three or more points of the same rank are connected by a corner, they form a polygon. This connection can recreate an object of any form or shape.

Techniques Used  In 3D Modelling

    • Box modelling – with this type, the artist uses a geometric shape such as a cube or a cylinder and shapes them until it resembles the desired shape. This process is carried out in various stages
    • Contour modelling – this is another type of polygonal modelling technique used but it is not the same as box modelling. The modellers develop the model piece by piece instead of defining an original shape. 

    • Spline modelling – this type of modelling is used in the industrial and automotive modelling processes. The NURBS mesh which is used, does not have any edges or face. This model is also compatible with various software.
    •  Digital sculpting – These 3D modelling processes have been integrated by the tech industry.
    • Procedural modelling – these refer to the designs generated algorithmically and they are not manually created by the artist. The objects and scenes are developed on the basis of user defined rules.



Other Techniques

  1. Image based modelling – these 3D objects are derived algorithmically from a set of 2D images that are static. 
  2. Surface modelling – this helps to create a 3D spline. The process involves a 2D spline and its difference from NURBS. 

Ensure that you study the different 3D modelling techniques to get a better idea and choose the one that is apt for your project.
