Pixar's Senior Scientist post

things i learned:

• that they actually stated the use of math in animation
• that they had to make a new physics engine for Merida's hair
• also that her hair is made of 100,000 individual elements

opinions:

• i liked how much work they put in to make Merida's hair seem life like
• i didn't like how many elements they needed to make her hair seem life like

question: why did it take so much work just to make her hair life like?
