Types of 3D Modeling – What You Must Know

Three-dimensional images have firmly entered our life, ranging from architectural visualizations to computer games. 

Three-dimensional figures can be seen on 3D images, and the process of their creation is 3D modeling using computer programs through 3D modeling services by 3Nitro.

It is becoming more and more popular due to the fact that projects carried out in this way become much clearer and more realistic than ordinary drawings and two-dimensional models.

A 3D model is a three-dimensional figure in space, created in a special program. 

As a rule, drawings, photographs, drawings and detailed descriptions are taken as a basis, based on which specialists create a virtual model.

For those who have just started to master 3D modeling, the choice of a method, or an approach to creating one or another form, often becomes an insoluble problem. 

But the right approach is almost the most important thing in creating a 3d model. 

Now you will learn what kind of modeling techniques are, and which are better to use for jewelry forms.

 Today there are only 4 modeling methods:

NURBS Modeling or Vector Modeling

It is widely used in precision engineering because every line or surface is a function of coordinates, and this function can be accurately calculated at any point on the surface. 

This allows you to create the most accurate shape of the model, regardless of its physical size.  This method is widely used in jewelry 3D modeling. 

A wide variety of geometric, organic and bionic shapes can be created.

Polygonal modeling

It all started with him. 

This is the oldest modeling method with which you can create absolutely any shape, but it is not always quick and easy. 

Polygonal modeling saves computer resources, so models created in this way are more often used for 3D visualization and in games. 

But this method is also actively used for jewelry modeling. 

However, the accuracy of this method is very low, and the designer has to do most of the work simply by eye.

Sculptural Modeling

After the advent of pixel technology (pixels with a height coordinate), it became possible to split a polygonal model into a very large number of faces, and work with it like real clay or wax. 

This method allows you to create the smallest details on a 3D model, and is most often used to create highly detailed organic shapes, as well as to create normal textures. 

In jewelry 3D modeling, this method allows you to refine geometric shapes, apply volumetric texture to surfaces and add natural distortions to models, as after processing. 

The accuracy and sizing in this method is at a conditional level.

Combined method

This modeling method includes techniques for creating a 2.5D shape on a plane from pre-drawn vectors or a black-and-white image. 

This method is used for modeling specific models for a milling cutter and has many limitations.  Well suited for creating flat ornaments and bas-reliefs.

For beginners, the easiest and fastest method of work is NURBS modeling. 

It can be easily mastered, and you can immediately create a large number of different forms of jewelry. 

But for professional work, you will also need to study sculptural and polygonal modeling.  This will allow you to freely create almost any, even very complex, shape of decoration.

Also, a great option would be to simply contact the 3d architecture company directly, who will do the work for you, especially when it comes to architectural objects. 

Turning to such highly qualified specialists, you can be sure of the quality of the work performed.
