3D Modeling 

3D Modeling is all about developing a three-dimensional object by recreating any real world object or any conceptual art. This can be achieved through different tools, and the process of creating three-dimensional objects using software is called 3D Modeling. Industries such as video gaming, visual effect creation in motion pictures or animated movies, and VR games have been using this process of 3D Modeling for decades.

The basic approach of developing a 3D Model is to use a set of two-dimensional polygons and place them together in a three-dimensional space. A polygon is a two-dimensional object with a minimum of three-vertices, such as a triangle, square, pentagon, hexagon, and so on. The following is an example of a polygon in a triangle shape, where you can view the object in a three-dimensional space:

Now, take this same polygon and add two more polygons in different directions/axis, and this will create a three-dimensional object.

Further in this section, we will apply the same logic of creating three-dimensional objects using a set of polygons and 3D basic primitives, such as a cube or sphere.
