## Abstract An improved integration approach for segmented 3D shapes using projected digitalized 2D pattern is presented. The digital 2D patterns are fabricated based on lithography techniques. Geometrical accuracy better than 0.5 ฮผm can be achieved. Contrast ratio of the fringe pattern can be prec
