It’s the moment that captivated fans anxiously awaiting the release of Frozen 2—Elsa attempting to run across the ocean, freezing the water as she moves.
That moment was made possible, or at least made easier, with the help of BYU professors. BYU News shared an article about the involvement of BYU computer science professors in the animation process for the new movie.
When filmmakers needed to make an adjustment to one of the scenes where Elsa is freezing the water, the animators would need to re-simulate the entire scene. The process of creating the animation can take significant time.

“If the animator invests the time to run a simulation then the director looks at it and says it’s not quite right, he or she has to start from scratch, change some parameters and run the entire simulation again,” said BYU professor Parris Egbert, according to BYU News. “That process will be repeated as many times as it takes for the director to approve it.”
Computer science professors at BYU created a way that allows animators to resize the animations of fluids. The method, called “fluid carving” uses a mathematical function to change elements of the picture.
“With our method, the animator can simply make it smaller and move on,” Egbert said.
