Understanding NURBS, T-Splines and SubD 

3D modeling is an incredible feat in computing. What made it possible are inventions like NURBS and T-Splines - mathematical models for representing three-dimensional surfaces. I was trying to understand the differences between different types of modeling, different available spline types, and more.

These are a few articles I went through trying to understand what NURBS is and how it is different from newer methods like T-Splines and SubD
