Two experiments were performed to rank different types of display formats common to CAD applications in terms of geometric information conveyed and perceived realism of objects. Display types tested were: wireframe, wireframe with hidden lines removed (HLR), shaded solid, orthogonal multiview, stereoscopic wireframe, stereoscopic HLR, and stereoscopic shaded solid. The results of the geometric information experiment indicated that the orthogonal multiview display was judged inferior to both the nonstereo and stereo pictorial displays and that the stereo displays were judged superior to the nonstereo displays in providing geometric information to the subject. Individual preferences among subjects, however, varied widely. The results of the realism experiment indicated that the flat shaded stereo, HLR stereo, and the flat shaded display types were judged to be equivalent and most realistic. The wireframe stereo, HLR, and wireframe displays were judged to be equivalent and less realistic. The orthogonal views display was judged to be the least realistic.
