3D Modeling

What is 3D Modeling? How is it Carried Out? Different Methods are Employed

In this article, we’ll look at the 3D modeling procedure. However, before getting more specific and looking at the many popular 3d models methodologies employed, we will first give the subject a broad overview.

If you’ve ever seen a sculpture, you already have a good understanding of 3D modeling. Simply put, 3D modeling involves using the techniques and tools provided by computer software to create a character or model with three dimensions (much as in the real world).

Let’s Look into It More:

Every 3D model utilized for computer rendering is made out of polygons. Hundreds, thousands, or even millions of polygons, each with three vertices or more, can be found in a  free stl files. So a 3D artist creates every polygon precisely as such? Fortunately, no! We can use tools like Maya and 3DS Max in this situation. These 3D modeling packages offer various modeling tools that an artist can utilize to construct a polygonal model.

Modeling in Modules

The simplicity of this modeling approach also comes with several drawbacks. For instance, a human head and neck can be modeled using modified spheres and cylinders.

To model a human head using NURBS, you would first generate an outline shape, then a set of curves that extend from one side of the profile shape to the other, separated by gaps.

In contrast, to live organic models, this popular stl files technique is more suitable for constructing inanimate items like houses, furniture, etc., because the shapes appear distinct, and the blending of various body parts won’t be seamless.

Model Surface Modeling

This popular modeling technique is primarily utilized in organic modeling. The 3D artist creates a spline cage profile for the 3D character using this modeling method. The splines intersect one another to give an utterly closed shape of the essence, in contrast to the NURBS approach. The 3D artist can utilize a surface modification to convert the 2D splines into a 3D-filled surface once the spline cage is complete. This method can be expandable at any stage of the modeling process to meet various requirements.

Polygonal Modeling

This is one of the few modeling techniques used in various modeling situations. This methodology is used with both organic and inorganic models. The fundamental concept behind this free 3d models strategy is as follows. First, the 3D designer makes the required model’s shape using the polygon tool. The model will then be splist into two parts and extruded to give it three dimensions. This subdividing and extruding technique is repeated until the model is finished. The artist really creates the polygonal mesh by hand in this modeling technique. However, this polygonal model won’t be smooth or perfect and will only have a few polygons. The artist would then apply a smoothing modifier to this polygon model to create a smooth-appearing, lifelike character.

Extensive Modeling

The benefits of polygonal modeling and NURBS modeling are combined in this hybrid modeling approach. It also offers some additional improvements. During subdivision modeling, the artist often starts with the polygonal model itself. Then, a sub-divisional model is developed from an existing polygonal model. Control points and lattices in the sub-divisional model can be pulled and moved to modify the underlying polygonal model. Using this modeling technique, the artist can determine the degree of realism that should be used in a specific location. As a result, regions with more extensive information needs can be given more control points and vertices, while other areas will maintain their base vertex density. This considerably enhances performance.


The model is created in the mind of the 3D artist using the modeling mentioned earlier techniques. Every modeling method will affect the model that is made with it. A pure polygonal mesh of this model is created, which is subsequently rigged and animated in compliance with the requirements. The rendering engine of the 3D animation program converts the scene, which includes multiple polygonal models, into a two-dimensional image or video.
