1. A method performed by a computer device for use in material processing of a two-dimensional sheet material, the method comprising:
obtaining information related to a desired design of a three-dimensional object;
obtaining information related to material characteristics of the two-dimensional sheet material;
defining a primary surface and a secondary surface of the desired design of the three-dimensional object;
defining a geometrical relationship between said primary surface and secondary surface, wherein
the secondary surface is a reflection of the primary surface in a two-dimensional plane, and wherein
when said primary surface is concave said secondary surface is convex, or when said primary surface is convex said secondary surface is concave;
providing, or otherwise creating, a digital instruction for a fully developed spreading and subsequent folding of a two-dimensional sheet into the obtained desired design of the three-dimensional object, wherein said digital instruction is based on the defined primary and secondary surfaces, respectively, and said obtained material characteristics; and
transmitting said digital instruction to an industrial robot for the spreading and subsequent folding of the two-dimensional sheet by means of the industrial robot.
