1. A computer-implemented method comprising:
projecting a boundary polygon associated with a first region of a three-dimensional (3D) object to a two-dimensional (2D) image plane, the boundary polygon comprising a plurality of contour vertices and edges connecting the plurality of contour vertices;
triangulating the first region in the 2D image plane to generate a 2D triangulation; and
generating a 3D mesh for the first region by mapping the 2D triangulation to the 3D object by connecting at least one pair of contour vertices with a path on a surface of the 3D object which corresponds to a straight line connection in the 2D image plane, and refining the 2D triangulation based on sample points collected along the path on the surface of the 3D object.
