Have you ever wondered what makes characters from Pixar cartoons look so realistic? Subdivision surface is the technique many 3D animation artists use to create more curvy surfaces, especially when it comes to faces, body parts, or clothes. The iterative method starts with a base polygon — a rough model of a future object — and divides each region into smaller ones, providing more flexibility and control to these areas. The best tweak of the subdivision surface is that the model remains smooth even in motion.^[1]
