An algorithm for displaying curved surfaces with hidden lines eliminated Is described. The surfaces are displayed as rectangular grids of straight segments which approximate those surfaces. The algorithm is essentially one of brute force. However, it divides the screen space into Enall 3D boxes to r

A hidden-line algorithm for displaying curved surfaces by line drawing is presented. The algorithm divides the screen plane into small rectangles, unlike Ohno's algorithm, which divides the screen space into small 3D boxes and exploits quadrilateral coherence and depth coherence. The present algorit
The programs are written in FORTRAN and are very short and simple. The computation time of the algorithm is short enough to handle scenes of high complexity. Hidden-line and hidden-surface problems have been discussed so often and solved in so many ways 1'2'3, that it might seem that they have been
