Harry Potter Magic

The most magical environment Double Negative created, however, was arguably the Hall of Prophecies, an infinite room filled with never-ending rows of crystal spheres on glass shelves. Inside the crystal spheres, prophecies in the form of holograms swirl within a plasma gas. “It’s the first time a fully digital set was used in a Harry Potter film,” says Franklin.

Trina Roy used the studio’s dnAsset and dnDynamite tools to create the environment. dnAsset, a Maya plug-in, manages complex geometry, like that in Gotham City for “Batman Begins.” dnDynamite is a rigid body solver built into Asset that effects a dynamic simulation. During a battle between Harry Potter (Daniel Radcliffe) and the Death Eaters within the Hall of Prophecies, the rows of shelves fall like dominoes, creating what Franklin calls a “waterfall of destruction.”
