One of the main goals of the animators was to create movement that mimicked the soft fluidity of the hand-drawn art found in older Disney animated films. Keane credited Disney 3D animator Kyle Strawitz with helping to combine CGI with the traditional hand-drawn style. "He took the house from "Snow White" and built it and painted it so it looked like a flat painting that suddenly started to move, and it had dimension and kept all of the soft, round curves of the brushstrokes of watercolor. Kyle helped us get that Fragonard look of that girl on the swing… We are using subsurface scattering and global illumination and all of the latest techniques to pull off convincing human characters and rich environments."
