Designated region projection printing
A system determines an object-design for a three-dimensional model of an object. The object-design may exhibit a design continuity. The system breaks the object-design in to spatial patterns corresponding to the discrete surfaces making up the outward surface of the object. The system then generates flattened patterns by projecting the spatial patterns into a two-dimensional plane. The system prints the flattened patterns on to designated regions of material sheets in an orientation that preserves the design continuity of the object-design. The regions may be extracted from the sheets and then joined at their edges to form a cover for object that exhibits the continuity of the object design.
