![]() ![]() And just trying to ensure that those braid pieces didn't crash into each other and would bend and move properly was a challenge for us. Michelle: We were pulling the hair from her head, weaving it through into a braid all the way to the end. But as the characters evolved, Disney decided to give both Elsa and Anna light-colored braids, in line with the Norwegian cultural traditions that inspired the movie. Believe it or not, Elsa was originally going to have black, spiky short hair. Narrator: You can see that clearly in "Frozen," which had over 50 unique hairstyles. Nadim: A lot of the technology from that movie pretty much still exists till this day or has evolved into a newer form. Narrator: This tube-grooming tool was the predecessor to Tonic, the hair-grooming software that Disney still uses today. That process allowed us to kind of control the way the hair would break apart and interpolate. Michelle: The idea was to sculpt tubes of hair that would represent the main blocks of hair. Meanwhile, to give the artists more power to sculpt the look of Rapunzel's hair, the team broke down her 140,000 strands into 147 different tubes. But in the movie, you see it gliding smoothly along. In real life, this hair would weigh 60 to 80 pounds, so it'd clump into a mass or drag on the ground, like a heavy tail. This allowed the artists to make Rapunzel's hair twist and turn in exactly the ways they wanted. Narrator: Engineers then created a program called Dynamic Wires, which combined physically based simulation with laws for determining the hair's behavior that defied physics. We knew we had a huge task ahead of us to go from basically that to 70-foot-long flowing hair. Michelle Lee Robinson: The only movie before "Tangled" where I think we had really even attempted simulated hair was "Bolt" with Penny. Accounting for all these interactions would require simulation, a way of automating the movement of elements like hair, fur, and cloth. The other characters were constantly touching, pulling, climbing, and rolling in it. You had hair interacting with cloth, with skin, with other hair. Narrator: Like wind or different sources of light or shadow.Īnd Rapunzel's strands interacted with the environment in ways never seen before. You have to kind of take everything into account when you're doing CG hair, even stuff that's not on screen. Nadim: It's not hand-drawn, where you're focusing more on the shaping and you could cheat. It had to have volume rhythmic curves, twists, and turns and a signature swoop in the front.īut that shampoo-commercial hair wouldn't be so easy to replicate in 3D. The bible set rules, like how Rapunzel's hair could never fall in anything resembling a straight line. To make Rapunzel's CG-animated locks look as appealing as Disney's hand-drawn ones, the filmmakers started with a "hair bible" created by artist Glen Keane, who was behind some of the biggest hair hits of Disney's 2D past. The goal isn't always to make it as realistic as possible, but rather believable within the fictional world of the story. Narrator: This emphasizes a key tenet of Disney's animated hair. Nadim: Every shot of every movie has a lot of bending the laws of physics. The story begins with a familiar storybook princess who in 2010 was seen for the first time in 3D.ĭisney's first major foray into 3D hair animation came with "Tangled." Rapunzel's 70 feet of hair was basically its own character in the movie, pretty much breaking every real-life law of motion, and not just because it was magical. ![]() Getting from here to here required over a decade of innovation. ![]() "Encanto" made history as the first Disney animated movie to represent the full range of hair textures, from 1A to 4C. With "Encanto," the studio figured out how to create coiled hair like Mirabel's with natural movement. But back then, Disney had mainly focused on straight hair, building on its previous 2D looks. Narrator: If you peel back the layers of Rapunzel's hair in "Tangled," you'll see just how complicated animating 3D hair can be.
