Title: Computerised display facility for three=Dimensional objects - produces steric views in succession which are viewed stereoscopically
Inventor: LUEBBERS DIETRICH WERNER PROF
IPC: G09G1/06
Filed: 1977-08-26
Abstract: The three-dimensional display system uses a computer to calculate from the coordinates of one view of the three-dimensional object, the coordinates of a second, spatially orientated view of the object w.r.t. a second observation point. Both steric views of the three-dimensional object are displayed one after the other on a screen and viewed by means of a special stereoscopic viewer. To improve the recognition ability, it is possible to eliminate by means of the computer, the edges of the sections of the object which are masked by the observer. The contour lines perpendicular to the boundary lines of the sections of the three-dimensional object are calculated for the spatially-orientated views and are displayed. The stereoscopic viewer can be removed from the screen when this facility is not required.
