The new code does computation before it sends hair off to the simulator to determine how other hairs would relate.

Pixar developed and internally released a new simulator, which is multi-threaded. This coupled with the problem of collision and intersection – while holding to the production schedule – made Brave’s hair simulation extremely complex.

If the ‘springs’ were too soft the hair would unwind, if the hair springs were too stiff, her hair would not move realistically. Hair is modeled using a series of mass and springs (springs connecting point masses). But very curly hair acts in a contradictory way: curls are very stiff, so the springs need to be quite rigid, but the movement of the hair requires a soft flowing quality that fights this property. Simulation team was headed by Claudia Chung (R) The curls themselves were an issue from a simulation point of view.Merida’s hair required much greater hair to hair (soft body) collisions than anything Pixar had done before.The previous hair system used by Pixar had to be seriously overhauled since: Earlier hair such as for the characters in The Incredibles had much more groomed hair, but here the character’s hair simulation needed to solve how to get this messy, tempestuous and unpredictable look while still looking attractive and flowing nicely with the animation. The Princess Merida’s hair was almost a three year process to get correct. In the 3.0 Toy Box Editor she can be found under the ' Disney Infinity Townspeople' category when ' Unfiltered', under the ' Non-Play Set Townspeople' category when filtered by ' Vehicles and Actors', and under the ' Brave Forest Siege Set' category when filtered by ' Toy Origin'.If her curls were unwound Merida’s hair would measure 4 feet long.In the 2.0 Toy Box Editor she can be found under the ' Sidekicks' category when ' Unfiltered' or when filtered by ' Vehicles and Actors', and under the ' Brave Forest Siege Set' category when filtered by ' Toy Origin'.3.0: She is available to be purchased from the Toy Store for Sparks.2.0: She is unlocked while playing in the Brave Forest Siege Toy Box Game.She subsequently became a Costume in Disney Infinity 3.0. She first appears in Disney Infinity 2.0 in the Brave Forest Siege Toy Box Game. Queen Elinor Bear Costume is a Sidekick version of a character from Pixar's Brave.
