The Curiosity Behind Surface Modeling
3D modeling is an incredible feat in computing. What made advanced CAD and surface modeling possible are mathematical representations like NURBS and T-Splines — systems capable of describing smooth, controllable three-dimensional surfaces with precision.
I started exploring the differences between various modeling methods, spline types, and how newer workflows like SubD compare with traditional NURBS-based modeling used in industrial design and CAD.

Why This Was Interesting to Me
What fascinated me most was how different modeling systems influence the way designers think and work. NURBS feels engineered and precise, whereas SubD workflows feel more sculptural and fluid.
Understanding these systems also changed how I looked at industrial design surfaces, automotive modeling, consumer products, and even how CAD software itself is built under the hood.
