Mathematics and animation

A thing I learned from this article is that to make Merida's hair in Brave, Pixar had to build an entirely new physics engine. Another thing that I learned is that Pixar used Subdivided surfaces extentsively for the first time ever when they made the 1997 short, Geri's game. I also learned that pixar does not have software much more advanced than what is accessible to the general public. A thing I liked about this article is that it showed how mathematics made huge advancements in animation. Another thing I liked was the pictures included in the article. A question I have about the article is, Do I really have to be amazing at math to be successful in animation or game design?
