| Abstract: | The intersection of Bezier surfaces is one of the primary aspects in Computer Aided Geometric Design(CAGD).An easy and shortcut alogorithm is presented that computes the intersection curve of Bezier surfaces.The developable ruled surfaces with the control vertexes of Bezier surfaces and transform the intersection of Bezier surfaces into the intersection of developable ruled surfaces are obtained. |
