Lecture 8: Mesh Representations and Geometry Processing (86)

Here is a paper from Pixar Animation Studios that goes more in-depth on exactly what they used for subdivision, cloth dynamics, creases, etc. It covers a lot of the concepts from this class and is an interesting read for anyone that is intrigued! https://graphics.pixar.com/library/Geri/paper.pdf

Based on the article, subdivision surfaces were advantageous to the usual technique of using trimmed NURBS because they did not require trimming and they had guaranteed smoothness of the model during animation. However new challenges came up since for example existing tools had been developed for NURBS models and could not be directly reused. Overall using subdivison reduces the effort required to design and use models since there is no need to hide patchwork seams.
