Systems and methods for generating AR content to virtually alter a real-world item are provided. The real-world item may be a deformable item including one or more flexible surfaces. According to an embodiment, a method includes determining the relative positions of a plurality of points on the real-world item. Based on the relative positions of the plurality of points, a 3D model of a virtual item is distorted to produce a distorted 3D model of the virtual item. The distorted 3D model may have substantially the same shape as the real-world item. AR content is then generated based on the distorted three-dimensional model.
