The apparatus depicts the three- dimensional object (1 Fig. 1) as plane projections (I, II, III) from three or more different directions (A,B,C) by means of coordinate data fed into the memory of a computer. The apparatus includes a picture screens 4',4'',4''' connected to a graphic processor 6, as well as control unit 5 for changing the location of the partial projection. A different projection of the object is depicted on each screen. Each screen is provided with its own image memory, each image memory storing a projection of the whole object in its respective plane. An altered location, of each component projection a,b,c can be depicted by means of its own picture screen 4',4'',4''' immediately on the basis of the data stored in the memory corresponding to the picture screen concerned. <IMAGE> |
