| Abstract(in English) | We present an efficient method for displaying space curves input by the user as equations. The topology (connection) of the curves is correctly displayed in whatever resolution. This is a consequence of detecting all the critical points of the curve and recursively subdividing the domain. Critical points are detected by interval analysis involving interval evaluation, mean-value forms, and Krawczyk forms. Our system does not involve complicated symbolic computation of resolvants or even require the curve to be algebraic. We apply this system to display surfaces by their occluding contours, which is the most natural representation for human visual recognition as compared with wireframe models and their rendering. |
