Stereoscopic display for design visualization

摘要

Two experiments were performed to rank different types of display formats 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 views, stereoscopic wireframe, stereoscopic HLR and stereoscopic shaded solid. Prior to the running of the experiments a review of the current literature on stereoscopic rendering and display was conducted to provide guidelines for the creation of the stereoscopic images. The results of the geometric information experiment indicated that the orthogonal views display was judged inferior to both the non-stereo and stereo pictorial presentation displays and that the stereo displays were judged superior to the non-stereo ones. Individual preferences among subjects, however, varied widely. The results of the realism experiment were 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 overwhelmingly to be the least realistic.
