Abstract
A method and system for generating a graphical display from data describing at least one three-dimensional object is disclosed. The method and system include determining if a current position intersects a portion of the at least one three-dimensional object. The method and system further include identifying if the portion of the at least one three-dimensional object is visually obstructed and removing data relating to the portion of the at least one three-dimensional object if the portion is obstructed in response to the determination if the current position intersects the portion and without determining a precise axial position of the portion of the at least one three-dimensional object. The method and system also include providing information relating to a plurality of characteristics of the portion if the portion is not obstructed and data relating to the portion is not removed and utilizing information relating to the portion of the at least one three-dimensional object to display an image of an unobstructed portion of the three-dimensional object.
