Unlike volume models, surface models, which are empty three-dimensional images, have a small fi le size, so they can be displayed, rotated, and modifi ed in real time. Th us, surface models of male urogenital organs can be eff ectively applied to an interactive computer simulation and contribute to the clinical practice of urologists. To create high-quality surface models,the urogenital organs and other neighboring structures were outlined in 464 sectioned images of the Visible Korean male using Adobe Photoshop; the outlines were interpolated on Discreet Combustion; then an almost automatic volume reconstruction followed by surface reconstruction was performed on 3D-DOCTOR. Th e surface models were refi ned and assembled in their proper positions on Maya, and a surface model was coated with actual surface texture acquired from the volume model of the structure on specially programmed soft ware. In total, 95 surface models were prepared, particularly complete models of the urinary and genital tracts. Th ese surface models will be distributed to encourage other investigators to develop various kinds of medical training simulations. Increasingly automated surface reconstruction technology using commercial soft ware will enable other researchers to produce their own surface models more eff ectively.
