Claim 0:
1. A computer-implemented method comprising:
generating a surface mapping function for mapping a first surface of a first three-dimensional (3D) object in a 3D space to a second surface of a second 3D object in the 3D space, wherein the surface mapping function is defined by a first representation of the first surface, a second representation of the second surface, and a neural network model configured as an intermediary between the first representation and the second representation to map a first two-dimensional (2D) representation to a second 2D representation;
selecting a set of points in the first 2D representation, the set of points comprising vertex points and internal points of a first 3D mesh, wherein:
the first representation of the first surface is produced by minimizing a loss function defined based on Euclidean distances between (a) output points of the neural network model using the set of points as input and (b) ground-truth points of the set of points in the 3D space, so that the first representation of the first surface corresponds to a mapping from the first 2D representation of the first surface to the first surface of the first 3D object;
the second representation corresponds to a mapping from the second 2D representation of the second surface to the second surface of the second 3D object; and
generating the surface mapping function comprises adjusting parameters of the neural network model to optimize an objective function, wherein the objective function comprises a distortion term defining distortion between the first surface and the second surface mapped through the surface mapping function;

applying a feature of the first 3D mesh on the first surface to a second 3D mesh on the second surface to produce a modified second surface, wherein the first 3D mesh on the first surface maps to the second 3D mesh on the second surface as determined by the surface mapping function; and
rendering, by a rendering module, the modified second surface.
