NURBS (Non-Uniform Rational B-Splines) modeling is based on mathematical curves and surfaces, allowing for smooth and precise 3D modeling. This technique is commonly used in industries like automotive design and product visualization. Software like Rhino and Alias are popular choices for NURBS modeling.

One advantage of NURBS modeling is its ability to create complex organic shapes with precision and ease. However, it can be challenging to work with compared to polygon modeling due to its mathematical nature.

Sculpting

Sculpting involves shaping 3D models as if they were physical sculptures, allowing for organic and detailed designs. This technique is commonly used in character modeling and digital sculpting. Software like ZBrush and Mudbox are popular choices for sculpting. One advantage of sculpting is the ability to create highly detailed and realistic models with ease.

However, it may require more computational power and can be challenging for beginners compared to other techniques.
