Types Of 3D Modeling And How Is It Useful Today?

The type of 3D modeling one needs to create a 3D model depends on the 3D object in question. This 3D object could be a car, a jet, nuts and bolts, and even characters from a movie. 

Polygonal/ Direct modeling

This technique of 3D modeling is concept-driven rather than measurement-driven. It’s akin to making something out of clay, where the object depends more on artistic vision than set dimensions. It prioritizes conceptual thinking and feels like sculpting “digital clay”. 

It is typically used today in the animation and video game industries to create your 3D product such as CGI (computer-generated imagery) movie characters and video game characters.

Here measurements don’t take precedence like in the case of parametric modeling, instead, it’s more about improvisation. A majority of 3D models today are built as textured polygonal models because they are flexible and because computers can render them quickly. 

Take, for instance, the 3D model of ice cream.

To create this 3D model using a polygonal modeling program, a unique approach is necessary. The shape of this model and the size/dimensions of different parts of the ice cream can be determined by pushing/pulling random areas of its surface. 

Smoothing operations bring this model to the next level. Time can be saved by duplicating the initial ice cream ball and by changing the size and the rotation of the copies. This sculpting technique gives us very convincing results. 

This goes to show that one can make any kind of 3D object using polygonal modeling. This type of 3D modeling is preferred by today’s artists; more often than not, the objects designed using this type of modeling are meant only for the virtual – and not the physical – realm.
