1. A method for designing three-dimensional (3D) objects for fabrication, the method comprising: obtaining a three-dimensional (3D) mesh comprising polygons; obtaining a two-dimensional (2D) image; receiving position information describing a position of the 2D image relative to the 3D mesh; and modifying the 3D mesh based on the 2D image and the position information to generate an embossed 3D mesh that is embossed with the 2D image.
