Abstract
This disclosure describes technology, which can be implemented as a method, apparatus, and/or computer software embodied in a computer-readable medium, capable of deforming internal geometry within an outer geometry to account for light bending due to refraction, for example, for real-time modeling of a gaze direction of a 3D computer generated character's eyes. In some implementations, internal eye geometry can be deformed to capture the effect of refraction in real-time such that the gaze direction of a 3D character's eyes can be modeled during an animation phase prior to a rendering phase in the production of a computer generated motion picture.
