Claim:
1. A computer-implemented method of generating an animation model of an object, comprising: obtaining one or more images of the object, the object including an opaque surface located behind a refractive surface; determining one or more reflection constraints, one or more refraction constraints, and one or more position constraints for constraining generation of a refractive surface representation; generating the refractive surface representation by optimizing a position of the refractive surface using the one or more position constraints and by optimizing one or more surface normals of the refractive surface using the one or more reflection constraints and the one or more refraction constraints; and generating the animation model of the object, the animation model including the reconstructed refractive surface representation, wherein the refractive surface representation represents the refractive surface in the animation model of the object.
