Types of 3D Modeling

Polygonal Modeling

Polygonal modeling involves constructing 3D models by manipulating individual polygons. This method is widely used for creating low-poly models, making it ideal for real-time applications such as video games.

NURBS Modeling

NURBS (Non-Uniform Rational B-Splines) modeling is based on mathematical curves, resulting in smoother and more organic surfaces. It is commonly used in industries like automotive and aerospace design.

Parametric Modeling

Parametric modeling utilizes parameters to define the shape and dimensions of a model. Changes made to these parameters automatically update the entire model, making it highly efficient for iterative design processes.

Sculpting

Sculpting allows artists to shape digital models as if they were working with virtual clay. It is widely used in character and creature design due to its ability to create intricate details.

Procedural Modeling

Procedural modeling involves using algorithms to generate complex 3D models. This technique is useful for creating large-scale environments and landscapes.
