1. A computer-implemented method for simulating breast appearance of a woman after a breast surgery, said method comprising the steps of: generating a three-dimensional (3-D) representation of an upper torso of said woman including an original breast, wherein said upper torso includes a neck, and wherein said original breast includes a right original breast, a left original breast, or both said right original breast and said left original breast; performing a 3-D contour analysis from said 3-D representation by recognizing and analyzing contours and a rate of change in said contours on said 3-D representation, wherein said 3-D contour analysis automatically recognizes and analyzes a first set of 3-D anatomical features and locations of said upper torso and a second set of 3-D anatomical features and locations of said upper torso; analyzing at least some of said first and/or said second anatomical features and locations to determine a plurality of 3-D breast-related surface measurements, or to determine a plurality of direct point-to-point breast-related distances, or to determine a combination thereof; constructing a virtual chest wall from said contoured three-dimensional representation by including a soft tissue envelope and skin color, wherein said constructed virtual chest wall results in a realistic image of said upper torso of said woman; and performing a simulation of a breast implant, wherein said simulation shows a resultant breast shape and position with respect to said constructed virtual chest wall, thereby simulating breast appearance of said woman after breast augmentation surgery.
