The three-dimensional personal computer graphics (DIM 3) was developedby the autheor. Input data were traced out of the maxillofacial cranium shape of the CT films by the cursor pen on the digitizer, and the computer graphics image was reproduced on the CRT and X-Y plotter. The reproducible accuracy of the graphics was satisfactory for use in diagnosis, surgical therapy planning and morphological studies in the field of maxillofacial surgery.
