Abstract: The computational mechanism of stereoscopic views is introduced, and the transformation of stereoscopic projection is inferred based on perspective projection. The paper has studied the method of creating stereoscopic projection based on signal viewpoint projecting transformation, i.e., by means of transforming the object being observed with shearing and translating transformation, thus obtaining the perspective view of the second (left eye) viewpoint from current (right eye) viewpoint. The proposed algorithm has theoretically been proved using projective geometry theory. An evaluation of results using AutoCAD has been carried out, proving that the proposed method is both effective and easy to be used.
