Abstract : Determining the topology of intersection curves is one of the important issue of surface-surfaceintersection problem used in Computer Aided Geometric Design. To compute the intersectioncurves, we first need to determine the topology of the curves. Thomas A. Grandine[1] presentedan algorithm to determine topology using partial derivatives of surface intersection equations.When the two surfaces meet tangentially, some differentiated values of surface parameters arenot exactly determined. This case is called a critical case. In this case, we find exact solution ofuncertain differentiated values using the tangent vector of the intersection curve.
