There has been a long-standing need for human figure simulations that are both accurate descriptions of the human body and at the same time adaptable to different user environments. This paper reviews developments by the author to meet this continuing need, especially the use of biostereometrics in high resolution human figure simulations. This research, including the use of biostereometrics spanned twenty years. The author's developments at Boeing were the "First Man" and "Second Man," representing pilots with surface lines having up to nineteen movable segments, and "Third Man and Woman," developed at Southern Illinois University at Carbondale, representing a hierarchial figure series. "Fourth Man and Woman," series 4.2, were designed at Southern Illinois Research Institute U.S. and its Siroco office in Washington State, consisting of polygonal descriptions derived from biostereometric data, appropriate for both line and raster displays. "Fourth Man and Woman," series 4.3, will be smoothed, clothed, and further incorporate hierarchial levels of detail.
